"Bite me." The brunet growled, as he panted, entire body shuddering and shaking.

Atsushi blinked.

They were in the midst of battle, one with the PM and one that their lives depended on.

They broke in to help Yosano escape Mori's grasp, since the man was quite serious when he said that he'd be keeping her, one way or the other, when all of a sudden, Osamu fell and crumbled like a withered flower.

One burnt to ash and dust.

There was a sweet scent, one of roses and for some reason a bit of rain, as the man collapsed, and he could feel his own mind cloud a bit, but he couldn't quite put his finger on what was going on. 

"Atsushi-kun. Bite me." The man almost ordered, and the….request (?) was oddly tempting. 

What the hell was going on?

"The scent of an omega…." One man hummed from the jail cell, where they were pretty sure Yosano was held in, sounding weird as he spoke, and it took a second for it to register in his brain.

Omega.

Sweet scent.

Omega.

He looked between Dazai and to where he heard the voice.

" Bite me! " Osamu hissed through his teeth, holding himself closer as he tried to get up, succeeding to only grab Atsushi's tie in anger and pull him down.

He wasn't an alpha. The orphanage director did the test on him. He was  nothing but a measly beta.

So why,

" Nakajima. " Osamu growled, making him swallow and then finally give in and bite the flesh of Osamu's bandaged neck.

Why the hell was his body becoming glazed with fever?

Why the fuck did he feel like he got thrown into a wall, or perhaps under a train?

"Omega? Dude did you jerk off lately? You fucking horny bitch." The other laughed, as the two exited the cell and luckily averted to the other side than where Atsushi and the brunet snuck to.

"Man, I swear I smelled a sweet little omega whore somewhere around here." The first one mumbled, making Atsushi's skin crawl.

Omega whore.

How dare them. Not only was he pissed because they said that about his friend, mentor and coworker, but also because of their tone. The voice was filled with mock, arousal, and obvious objectification. 

Like that's all that omegas were to these people. Objects for sexual gratification.

He wanted to jump in and fight them.

Before he felt the brunet's hand on his locks, reminding him that he was still, now angrily, biting into his neck, with his mouth full of blood.

He pulled back, flustered, still a bit angry  and mostly confused.

Confused as to why he was feeling so much and yet so little.

It was…weird.

For some reason, he felt depressed, angry, frustrated, aroused and in general overwhelmingly underwhelmed by all of that.

"Well. This was not on my to-do list, but I promise you I'll probably kill myself before you find yourself an actual partner so don't worry much." The brunet shrugged nonchalantly, as he got up, legs still shaking and throat bleeding through the many layers of bandages.

Kill himself.

Partner.

Mates. They were mates now. How.

"I, I'm not an alpha," He tried, but the man wasn't even listening to him.

"Talking later, saving Yosano-san now." Osamu shrugged, as he headed towards the cell.

And Atsushi followed closely behind, baffled, confused and extremely anxious about everything that was currently going on.

He still followed, trailed behind, as they broke into the woman's cell.

Once two became mates, omegas, even in heat, wouldn't give off any scent so as to not "tempt" other alphas. That's what they taught them at the orphanage. 

The omegas would still go through heat though and feel full effects. And unlike the orphanage preached, as he found out from books, heats weren't a "wonderful experience" for both alphas and their paired omega.

It was hell for the latter.

They would have high fevers, abnormal pain in their abdomen, not to even mention black outs, hormone imbalance, cramps, and a clouded mind. This was either a preheat induced reaction or a near miracle that Dazai was both comprehensive and walking during his heat.

And since Osmau was nothing short of an anarchist when it came to the laws of reason, life and even physics sometimes, he would bet that it was once again the latter.

He watched as the man grabbed a stray paper clip and picked the lock, before they slipped inside of the cell quietly.

The plan was simple.

Get Yosano out of her restraints and book it.

They were surprised, well, he was surprised to see the woman in a room, probably sedated, glaring angrily at the ceiling as she laid there.

He wanted to ask questions but decided against it.

Atsushi walked over immediately and checked her over, making sure that there were no injuries, as she looked over at them and blinked, rubbed her eyes even.

Before she grinned.

"Took you long enough. Let's get the fuck out of here." The doctor bit out weakly, as she tried to get up, only to fall back down on the bed.

That's when the young man picked her up and apologised with it with his eyes, getting an eye roll in turn, as the woman put her hands on his shoulders and rolled her neck.

"Let's get the fuck out of here indeed." The brunet smiled, but for some reason…he felt some form of estranged emotion emitting from the other.

That was odd. Weird.

He's read that mates often feel one another's emotions but he was also confused as to how they could ever even become mates because he was no alpha.

He never had ruts, he presented as beta according to every document and he never had issues being around omegas, even in heat.

But he bit his tongue and nodded, deciding that they should save the doctor first, bring her back so she can get checked up by a medical worker for the obvious drugs she had in her system and then talk between each other on what the fuck happened between them.

They got out pretty much quietly after that and managed to leave through the same opening that they sneaked in by.

Only one who caught them was a short man with a hat.

Although, his eyes immediately went straight to the bite on Dazai's throat which was still bleeding profusely, and he looked baffled enough, was confused and puzzled to the point where they managed to swiftly run by him and get the hell away from the building.

He couldn't help but fear the man going after them, so by that point, he put Yosano down and took a second to transform, with the two of his colleagues getting the message pretty easily.

Osamu got on top of him first, and grabbed him by the throat, for balance while Yosano got on behind the brunet and held onto his waist for support.

Suddenly he was the one feeling weird.

But he managed to reason with himself and get the uncomfortable feeling out of his stomach, as he instead took his frustration out on the dry cement and ran as fast as he could towards the agency.

They were pretty successful, he'd say. Because Yosano was taken back safely and they managed to either lose the redhead from before, or perhaps they baffled him enough to the point where they probably ran off faster than the man could gather his shit and chase after them. 

Either way, he was happy. And finally, once they dropped Yosano off at Fukazawa's office, with the man immediately asking about the wound on Dazai's neck, and asking what the hell happened between them, did they look at each other.

"A lot ." Osamu simply said, as he grabbed Atsushi's hand and pulled him closer. "If you don't mind, we have quite a bit to talk about." The brunet continued, as he dragged him towards the doors. And whilst he did want to talk about it he also didn't want to rudely leave Fukazawa's office.

Still, he didn't have much of a choice as he got dragged off by the brunet, and into one of the more private areas.

Only once the man closed the doors, did he collapse and make the tiger almost shriek in surprise.

"Dazai-san, what the," He tried, as he kneeled before the man and grabbed his face, uncovering it from the brown locks of hair and letting those blown out pupils connect with his own.

It was a miracle that the scent didn't hit him before. But now that it did, in its full power, his knees were shaking and there was an urge screaming at him to grab the man, pin him down and,

That was enough. He shook his head, but no matter how hard he shook it, how hard he bit the inside of his cheek, the thoughts wouldn't go away. 

"My suppressants ran out." The brunet stated, as he loosened up his collar, trying his best to stay as calm as physically possible, yet failing the slightest bit as his mind began hazing over. 

"They're officially not in effect at all anymore." Osamu bit out again, as he spread his legs, clearly in great pain and discomfort, which made something inside of Atsushi actually tear him apart. It felt like he was failing for whatever reason. 

"Get me out of here and back home now. "

"How?" He couldn't help but ask. Because he knew that Dazai would not appreciate Atsushi talking about this entire situation right now and that explaining everything to their boss first was out of the question.

"By grabbing me, throwing me over your shoulder like a sack of potatoes and running out of here." The brunet glared, making him take a deep breath. Before he picked Dazai up, and made him grab onto him.

The tiger couldn't help but shiver, as the heated, too heated skin touched him.

He was close to giving in to whatever the hell was clawing at his skin, making his head spin and body almost seize.

They needed to talk. And they needed to get out of here.

So, he ran as fast as he could, through the office, and prayed to god they didn't get fired over this, as he looked down in his arms, noticing that Osamu was nuzzled up into his chest, sniffing at his scent gland like a drug addict might ingest their substance of choice.

And he shivered.

"Dazai-san, that tickles." He tried, as he fought the urge to just….pin the man against the tree that he just ran by.

"Alpha." Osamu mumbled instead, as his scent strayed from the rainy one and began smelling more….like a rose in full bloom. 

The scent was wonderful. It was addicting. It left his mouth watering. And he hated it.

Hated it, because Osamu was very much not in his right mind right now.

And hated it because he was reacting to that in such a way.

He bit his lip and decided not to talk at all, instead, as he walked up to Dazai's place.

Being inside of an estranged building, during one's heat could make an omega go into a frenzy due to unfamiliar surroundings. And the last thing he wanted was to give the brunet more stress during his heat.

Dazai suffered through this entire thing and even had to make Atsushi bite him just so that they wouldn't fuck their mission up and he'd be damned if he added more stress to the vournable man at a time like this.

He slowly searched for Dazai's keys inside of the said man's pocket, first inside of his coat and then as a last resort inside of the back pocket of his pants, which made the omega mewl and grind against his hand, but all he did instead of listening to the screeching voice inside of his head was grit his teeth and kick the doors open as soon as he unlocked them, before he slammed them shut.

Then, he walked over to the brunet's bed and dropped him down, feeling his hands shake and body scream at him to attack the brunet right now .

To get inside of the bed, lay atop, and claim what's rightfully his.

And the thought made him sick. This was his mentor. Someone who helped him, gave him a chance at a better life and someone who took care of him, helped him out of tough situations and taught him about his own emotions as well as how to deal with them.

Yet here he was, objectifying him, sexualizing him, just like those motherfuckers from the PM headquarters, because of his secondary gender.

He hated it. Hated himself for it.

"Don't leave." Dazai bit out, with the last bits of his energy, as he reached out and grabbed his long belt from behind him, making him bite his lip.

"Dazai-san, if, I don't think I can stay." He admitted, tried to explain to no avail.

"Withdrawal. Remember." The man panted, as he tried to sit up, only to fall back down, clearly trying his best to stay sane and present.

"Mated couples cannot leave during one another's heat and rut. Atsushi-kun stay." Osamu mumbled again, nails drawing blood from his cheek as he tried to keep himself coherent.  

"If this was only about me I would've made you leave." 

Something about that didn't sit right with him. Made him frown and grimace.

"But this can trigger you into an early rut." 

"If you go, you'll be scared, confused and alone. And it can be dangerous. You can be dangerous." The man explained, as he slapped himself and then got up shakily to sit, almost crumbling in pain right after.

"Dazai-san I'm not an alpha!" He bit out, as he glared at the man, suddenly very irritable.

"You are. " The man bit back, equally as frustrated as him, voice laced with anger.

"At the orphanage, I don't know who or why, they probably injected you with blockers by the looks of it." He opened his lips to deny it, but….

He couldn't. He didn't exactly have any idea what they were injecting him with every now and then and if any of the "shots" he'd get were alphan blockers. 

If they were, then that would….turn his whole world apart. He was grateful in his life for one thing and one thing only. The fact that he was a beta. Betas didn't have to deal with the unfortune that alphas and omegas had to deal with every three months.

They didn't get heats, didn't get ruts and they could…just live their life. 

If he wasn't blessed even in that way, he might actually cry.

"But they don't work after you've mated with someone." Osamu coughed out, as sweat rolled down his forehead, entire face red with the fever by now, and breath hitched.

"And they certainly can't hide your secondary gender from anyone else, even before this, you reeked of a young alpha." The brunet rolled his eyes, as he unbuttoned his shirt and shrugged off his coat, sweat slicked body trembling.

"Atsushi listen to me. I don't want this either." He declared, as he gripped the straps and pulled him in by them, in irritation.

And he supposed neither of them wanted the connection that made their relationship as awkward as it will most likely become.

"I did this because," The brunet began, before crumbling to the heat and losing himself a bit, brown eyes blinking rapidly, trying to keep it together. 

" Because we had to take Yosano-san back." And all of a sudden, the irrational anger from before disappeared, as he smelled rain again, oozing off of Dazai. He seemed…sad. Somewhat dejected and most definitely disappointed.

"And if they smelled me, if Mori caught a whiff of me there, we'd be screwed." He signed, releasing him and falling back against the pillow, bedframe and the wall, head connecting with it rather harshly. 

"You have to understand that this was the only way."

He bit his lip and took a second to think it over.

"I took five suppressants this morning but it wasn't enough apparently since my heat already began by the time I downed them."  Five. Five. He didn't have to be a doctor to know that that was not good nor smart on Dazai's part.

But then something worse registered in his brain. Suppressants were a preheat medication that could be used to hold off heats without the dangerous side effects of heat blockers.

With that said, taking them once the heat starts can result in side effects such as intense vomiting, liver damage, depression, anxiety, permanent side effects and even aneurysms .

He wanted to almost scream at the brunet for what he did to himself.

But instead, he just glared down in disappointment, as he crossed his arms.

"It's my fault and I do apologize but still ." Atsushi wanted to tell Dazai that he did not blame him for the situation. That he was angry because the bruent brought himself in danger but he couldn't, because he was too busy trying to control himself as he stared at the clearly distressed man, disgusted by the way that his body still reacted to the omega, even if the brunet was just trying to talk to him about a rather serious issue.

But he couldn't. His mouth was watering yet his lips were cracked dry as he sat there.

"Stay."

The words made his face soften and hands drop.

All of a sudden, he felt powerless against the request.

"We can discuss this later." Dazai sighed, burying his face in his hands.

"Just calm down and help me out while you're at it." And he wanted to. But he had no idea how to help the man, nor if it was safe for him to stay in the first place.

"Give me my suppressants they're in the bathroom,"

"No."

The man blinked.

"No?" He asked, surprised and baffled by his reaction.

"I might be dumb but I've read up on omegas before." Atsushi reaffirmed, as he sat on the edge of the bed, because his own knees began feeling quite wobbly.

"It's dangerous to take suppressants during heat." The brunet closed his eyes and took a rather deep breath.

"Atsushi. I'm in heat. You're an alpha." Osamu began, pointing between them.

"We're mated. If I don't down half of that bottle, you're going to be triggered into rut and we are going to do it." He continued, and both of them knew what do it meant in this context.

"If that happens not only will that alter our relationship, but strengthen the bond." He frowned, and was still firm on his decision, no matter what.

"I don't have any contraception on me, by me, or in my vicinity." The words made him flush and almost crawl out of his skin, because of the implication, but he still stubbornly stood there, sat, on the bed. 

Because he wouldn't just… give the man the suppressants while knowing damn well both what the side effects were and how many the man already ingested.

"It is basically dumb for us not to take the suppressants." Osamu mumbled, tired, exhausted, and barely conscious.

"I'll just…control myself." He bit out, as he dug his claws inside of his arm, the scent around them making it hard to breathe.

" Control yourself?" Dazai laughed, dryly, as he glared at Atsushi as if what he said was the most ridiculous, baffling thing ever.  

"You're a new alpha going into your first rut by an omega in heat." The man carried on, tried to explain, to make him see how ridiculous he was being.

" Your omega." The words, to his mortification, made him shiver.

"You have to have to be kidding me." The brunet finally finished, leaning back towards the wall, his unbuttoned shirt falling off his shoulder.

God the skin looked nice. Dazai's skin was pale, pretty, soft and,

He had to get his shit together.

"No. I'm not giving you the suppressants." Atsushi bit out, trying to back off a bit.

" For God's sake! " Dazai got out in frustration, grabbing his own hair.

"Fine! At the very least get us contraceptive pills." 

"But you said that us separating," The boy began, but got interrupted by a pillow being thrown at him by the brunet.

"I know. Which is why I told you to give me my suppressants. But since you want to be a caring alpha, then go and get some pills and prepare for the most disgusting week of your life." Osamu bit out, as he leaned down on the bed and grabbed his blanket.

And Atsushi, he thought about it for a second. If…if they ended up so crazed by their secondary gender….maybe it indeed was better to be safe rather than sorry.

So, he got up with great effort, and began heading to the doors, fighting the urge to return to Dazai and crawl in next to him, help him out of those clothes, breathe in the scent radiating in the room, take him apart slow and careful, please his omega,

Stop. He had to stop.

He reminded himself that neither of them liked each other and that this was all a matter of convenience and that the whole reason why they were mated was because they had to do it.

Atsushi quickly opened the doors and ran to the pharmacy and then back, in a record of five minutes.

On the entire way there he felt…angry, depressed, like he was missing something, like the air without the smell of flowers was worthless to him, like he couldn't breathe due to the lack of a floral scent, and as if him leaving would result in a great catastrophe.

No matter how much he tried, how fast he ran, he felt like each second that he took was wasted.

And yet…

And yet when he arrived, even in front of the doors, he almost didn't want to enter. 

If he thought the smell was strong before, it was twice as strong now. And he wasn't even inside yet.

"Lock the doors." Osamu growled, upon his entry, and Atsushi had to hold his breath.

There he was, his mentor, in his bed, laying under the blankets, hand… clearly doing something down there.

"Lock, the, doors!" He said again, more urgently, voice breaking off each and every time.

"Yeah," He stuttered out as he did as he was told, hands trembling so hard to the point where it took him more than a minute to complete the task.

Still, once done, he stood by the doors, afraid to approach.

"It hurts. I could've just taken my suppressants and slept it off like I've been doing for the past twelve years but you had to go and mess my routine up." The brunet growled, and all while he was glad that he could for once tell that the brunet wasn't being dramatic, that Dazai was like an open book right now, he was also terrified. Because Dazai really seemed like he was dying and withering, in the worst pains imaginable.

"Atsushi-kun, it hurts." The brunet bit out again, making himself seem so small, even though he actually towered over the tiger. That's what pissed him off the most when it came to dynamics.

The fact that strong people, like Dazai, crumbled and withered under their nature. It wasn't fair. For some to suffer just because they were born one way or another.

It wasn't "just nature" or "the beauty of life" it was literally humiliating and probably traumatizing. 

"Can I…help?" He asked, gulped, as he stood there, still holding back.

"Let your instincts take over. It's going to be probably disgusting but it'll be better than both of us suffering." Dazai muttered, as he continued to move his hand under the blanket, and seeing the man so desperate, so….defenceless made the ugly beast inside of him want to take over.

But he fought it.

Fought it as he approached the bed and then carefully climbed inside.

"Closer. Come closer." Dazai pleaded, ordered, said, as he crawled into the tiger's space, almost as if distance hurt him. 

Atsushi did as he was told, having to bite the inside of his cheek until it bled in his mouth to stop himself from violating the last barrier between them that their instincts were trying to break.

He hugged the brunet, instead of doing any of the downright nasty things that his "instincts" told him to do and let the man nuzzle into his throat, feeling him bite, lick and sniff the skin there, one hand around Atsushi, pulling him closer, while the other worked on himself under the blanket.

Atsushi could hear his heart beating out of his damned chest.

Difficult. This was difficult.

"You smell good," Dazai mumbled under his breath, each word spoken against his skin, as they laid there.

"Dazai-san, take the contraceptives." He reminded hoarsely, as he passed the pills he got from the pharmacy down the road, with the brunet weakly mewling as he moved.

"I can't bring myself to move. Feed it to me. Put it in my mouth." The omega got out, as he pulled back, and only now could Atsushi see the true extent of the effects that Dazai's heat had on him.

Since he was suppressing it almost as soon as it started, he seemed to be doing…terribly. His eyes were red, he was clearly crying, his entire body was a shaking mess and his skin was so hot that he felt warmer than a heated stove.

Atsushi hated to see him suffer like this.

But still, he out one of the pills inside of Osamu's mouth and watched as the brunet swallowed, before Osamu leaned into his throat again to kiss his skin, making him shudder. 

He could feel the man sucking one spot in particular that made the beast inside of him purr in dark, almost hazy lust.

"That's my scent gland, right?" He asked, just to busy them both, trying to avoid the unavoidable.

"Yeah. Smells so good. Satiates me." Dazai answered honestly, as he licked the place again and moaned at the taste. At Atsushi's taste.

God, it was hard to keep himself in place.

"But it won't do. You'll have to do it. Our instincts will take over soon enough." He chuckled, dryly, as he pulled back to look at the tiger.

"Soon, you'll see me as nothing but a womb to impregnate and I'll see you as my owner." The brunet laughed humorlessly, brown eyes waging wars against gods for making them this way. 

"That's just our code." 

Osamu seemed to hate their nature as much, if not more, than he did.

And that's what made this situation as messed up as it was. Both of them hated it but they had to do it.

"I suggest we do it first while still coherent. Because after, we won't get to go as soft." Dazai spoke up, but his tone was far from someone who wanted to do such a thing. "If..if we don't do it now, it'll get too rough once your rut hits." He explained, which made Atsushi frown.

He hated it. Hated the fact that they had to fear what would happen once both of them were pretty much unwilling witnesses to what their bodies craved.

Still, he nodded, carefully, and trailed his hand down to Dazai's own, closing his eyes.

Hot. The touch felt like burning metal branding into his flesh.

" Alpha, " The omega sighed, as he leaned into the touch, and to his surprise, maybe mortification, and definitely arousal, the man's hand was not where he thought it'd be.

It wasn't on the brunet's…. dick, no instead it was down there.

And…there was a lubricant down there yet no bottle of lube in sight. 

Generally, he knew what happened during heats. For female omegas. Male omegas…were rare. And he was almost ashamed to admit that he never read up on them much. 

"Lower. Please." The brunet begged, drunk off of his touch, mind clouding at the pheromones floating in the air around them.

And god, he could smell it. Smell roses all around him blooming even inside of him. He had no idea how that was possible, but his brain clouded even more as his shaky hands pulled Dazai closer, one trailing down to the slick and gathering it onto his fingers, before they joined Dazai's , inside of the man.

The brunet melted in his hands, but as he watched the man's face he could tell that it was only because of his heat induced crase. Which kind of…hurt.

He wanted the man to feel good during this sure, and he had no previous feelings for the man from what he knew but.

The fact that this was just their biology making them like this felt…wrong.

In a sense, they were stuck in a hopeless place and they had to depend on one another as they slowly lost their sanity.

So, he tried his best to push his thoughts aside and focus on the brunet's pleasure first and foremost.

As he moved his fingers it was mostly his body taking charge as he allowed his instincts to do what he hoped felt good, with Dazai responding quite genuinely to his advances, small little sighs and soft little content noises leaving his open lips in the process.

Dazai looked beautiful. He had a pale flush, as the fever slightly calmed down, due to his involvement in the activity, likely, and he had a drunk dazed little expression that was almost drowsy as they laid there. 

"Atsushi-kun." The man sighed, and cuddled closer, rubbing their bodies together in a desperation he hadn't ever seen the brunet show before.

"I need you to do it." He mumbled, as he ground down on his own and Atsushi's two fingers, the digits brushing against one another inside of the heated, wet hole. He was barely holding back as it was and the words, the grinds, made it that much harder to keep his cool. "I'm asking quite a bit from you right now, aren't I?" The brunet laughed breathlessly, as he kissed Atsushi's neck and drew a shiver out of his body.

"I'm sorry that I've forced this upon you but we had no other choice." 

Again. The tone sounded almost angry. He hated how Dazai thought that Atsushi would be mad at him in such a situation. They were in enemy territory, Dazai was vulnerable and the only thing that could save their ass and help them save their friend was doing this.

He couldn't possibly be mad at the brunet for requesting at least a bit of his assistance.

This was life or death, not just a matter of Osamu's dignity. And by the sound of those alphas, if Dazai went alone, if Atsushi wasn't there to bite him…god, he didn't even want to imagine what could've happened.

This and the fact that Dazai so calmly told him he'd kill himself in the midst of his other apology, made the tiger feel sad. He didn't want anything bad to happen to Osamu. 

He didn't want the man to raise his hand against himself or blame himself for what happened, and most of all, he didn't want Dazai to think that the tiger blamed him.

"I don't mind." He whispered, as he pulled his fingers out of the sensitive man, other hand going under Dazai and to his hair, as he allowed his instincts to take charge, body positioning them close to one another, laying the man on his back and prodding his hips up as he unbuttoned and unzipped his pants.

He took a second to…breathe.

Took a deep, deep breath, one filled with rose and one that made his mind even less coherent as he stared at the omega below him.

He wanted to…cherish Dazai.

It was dumb, but even amidst this uncomfortable moment between them, he wanted to somehow give the brunet some comfort.

He wanted to make it feel better. But he didn't know how to.

"Can I kiss you?" He asked, as he leaned down, seeing the man avert his gaze, somewhat puzzled by his question.

"I'd prefer more intimate stuff once I'm under it. But if it makes you feel better," The man began, before the tiger shook his head.

"No, I want to do what makes you feel better."

That made Dazai pause and blink.

"Why?" He asked, genuinely confused.

And Atsushi couldn't help but wonder what the hell that meant. Is it just that their dynamics don't call for genuine care between them? That the omega's fulfilment, content and comfort weren't in the picture even during such a… sensitive time for them?

Or is it that Dazai has been only ever treated that way during his heats?

Either way, the thought of the two possible scenarios made him feel bad for the man.

"Please tell me how to make it better for you." The tiger asked quietly, as he nuzzled into the place he bit a few hours prior, and gave it a gentle little kiss.

"....I don't know. Do whatever feels right, just..no kissing until I'm completely under it." The brunet muttered quietly, his voice strained and body grinding up against Atsushi's out of instinct.

The tiger nodded, and slowly pulled himself out of his underwear, his dick twitching in his hold as he did so. He felt oddly sensitive and weirdly… needy . 

He felt like he needed the brunet. Needed to put it in, to fuck him slow and deep, to hold him, kiss every inch of his skin, embrace him the entire night and use him throughoutly.

The last thought made him sick. 

As Atsushi carefully pushed inside, he stifled a groan against Dazai's throat and felt like he wouldn't last a second inside of his wonderful, warm, wet omega that seemed to mewl and almost purr in content at his intrusion.

His omega. Dazai was not his in fact. Dazai was a person and not property, the tiger reminded himself as he rocked fully inside, his hips flush against the man's plump behind, feeling Dazai's legs hook around his waist and his nails dig inside of Atsushi's back.

" God , what the hell did they feed you?" The brunet muttered under his breath, already panting, as they tried to gather themselves, get used to the overwhelming sensation.

"How the hell are you so big? That's unfair, Atsushi-kun." Osamu whined, as he pulled away from the tiger's neck, chest rising and falling with each breath that he took.

The tiger flushed at the words and averted his gaze, clearly embarrassed by it, which drew a breathy little chuckle from his mentor and made the brunet finally seem a bit less tense.

"Imagine being flustered about someone calling you big. God, you're such a cutie." The omega grinned mischievously, before his grin turned into something of a breathless moan, as Atsushi moved to a more comfortable position, feeling Dazai's nails dig further inside of his skin.

Osamu was so wet, so warm, so goddamn tight around him that Atsushi couldn't breathe .

It felt so good. It felt amazing. The man's floral, rich scent made him lose his mind and his hot body, eroticly flustered face, blown out pupils, only drove him more mad.

Oh, how he craved the man. How much he wanted to begin pounding away until he was cumming. God, he needed it. Wanted it. 

But he held back, and tried to let the man get used to it some more, before he slowly, gingerly pulled back just the slightest bit, before grinding back inside equally as torturously slow.

" Alpha, " Osamu called out, as he hugged the tiger closer, his body shaking with effort to stay conscious, clearly slipping from his sanity and giving into his instincts as he began slowly but surely grinding back into the slow, careful, experimental little grinds.

"Faster. Do it faster. " The omega got out, in embarrassment, which made him blush even more as he kissed Osamu's throat again, bandages slipping and showing off countless scars as well as his claim on the man.

God, as soon as he saw it, he lost it.

He fucked up into the brunet's body so hard that Dazai's head almost hit the bedrest.

And it drew a scream of his name from the brunet.

One that was littered with nothing but pleasure, as the man made his back bleed, uncut, sharp nails tearing his shirt apart and Dazai's feet digging into his waist, trying to feel that sensation again.

That reaction made his control slip. Completely.

Before he knew it, he was under a trance. His hips were moving on their own, fastening the pace, and one hand under the man's back, pulling him into each thrust as the other caressed down the bare chest, Osamu's open shirt swimming around him, pulling itself up and down the bed as he got fucked ruthlessly by the alpha atop him.

Each time he pushed in, he watched as Osamu pushed his body down against it and whined, threw his head back and bit into his own hand, eyes tearing up and other hand coming back to his face as well, trying to hide how vulnerable and desperate he looked, as he continued to bounce down on it, back arched like a bow and cock weeping.

The sight was…addicting. Almost as addicting as addicting as the fragrance of hormones around them.

And Osamu was almost as gone from the pleasure as Atsushi was.

"Dazai-san," He bit out, as his hand travelled to the brunet's abdomen, touching his stomach and groaning in pleasure as he saw the man look at him, fucked out and needy, almost like he might break if Atsushi stops.

"Fuck. I'm really about to cum before a virgin." Dazai chuckled humorlessly, as he gripped Atsushi closer, which made the tiger bite his lip and hide his face away into Dazai's throat again.

He was doing well. The man was feeling good.

The sheer thought of pleasing the omega made him shudder and bite gently on the spot that was slowly healing, before he gave it a soothing little lick.

" Fuck. " Osamu called out, instead of his name, as he came, back lifting off of the ebd completely and his entire body trembling with it, as Atsushi continued to gently help him ride his orgasm, slowing his thrusts down, before going to pull out, only to get pulled in again, Dazai's feet digging inside of his back as he got grabbed by his tie. 

"Don't you dare stop." The brunet growled, which made him bite his lip and grind inside again, speeding his thrusts up back up to that pace that made Osamu break down.

He was too close. He was about to cum.

But Osamu didn't want him to pull out.

He seemed like he might truly kill Atsushi if he stopped.

"It's fine to cum inside. I took the pill. Just, just fuck me." The brunet whined, as he hugged Atsushi closer and allowed his legs to slip off weakly, dick almost immediately getting hard even though he just came, and body burning up. "I'm in heat, Atsushi you said you read about that. I need you to fuck me for days. " Atsushi shivered at that, imagining doing this for not minutes, not hours, but days.

They would be a mess by the time they were done. 

"So, you better brace yourself and use what's yours now." He opened his lips to tell the man that he wasn't anyone's property, but all that came out was a strangled little groan as he felt Osamu drip around his dick and spasm.

"Since I'm your property for a while, you have to take care of me."

Take care of him. Atsushi wanted to do that. Atsushi wanted to take care of the man, to help him through this, to give in, to give him everything that the brunet wanted, to bend his knees to his chest, make him hold his legs spread wide open, watch as Dazai's nails cut up shapes into his lower thighs as Atsushi fucked inside time and time again, and he was losing it.

Losing his will to fight the instincts and losing any sense of reason as he stared at how beautiful the man actually was. Always so handsome, so perfect, so smart, so intelligent, staying so comprehensive even during this, god he wanted to worship him and comfort him, make Dazai feel better, wanted this to be real,

Pause.

Real? Did he truly want that? Did he….want Dazai in a romantic way? 

Or was this once again a thing of his instincts. Either way, he bit the thought and swallowed it down, focusing all his energy, all his thoughts and all of his actions on simply pleasing the omega until he was satiated enough.

"Good, so good," He gasped, as he held back from cumming, in so much pain to the point where he was shaking.

"Let go. You've lasted long enough for your first time, you're gonna give yourself blue balls." Dazai mumbled from below him, as he spread his legs wider, a fresh new wave of slick wrecking through his body and coating Atsushi's cock entirely.

And he did just that. Within seconds, he was thrusting inside as hard as he possibly could, before shoving as deep, as hard, as he possibly could and choking on his br4ath and spit, as he felt something inside of his stomach snap.

What the hell was that?

That something literally popped form the head of his kock and made him panic, want to pull away, before he quickly remembered that alphas had knots.

Shit. He pushed in again, as far as he could, and whined as he continued to orgasm, his body becoming feverish, the need to claim, own and fuck his coworker making him tremble and hang onto him like he might fall apart if he let go.

"Atsushi, kun," Dazai weakly panted from under him, making him pull his nails out of the man's soft skin and kiss his neck apologetically, feeling like if he moved to actually see the brunet's face, he might lose all sense of sanity.

"It's, it's so hot," He hoarsely got out, breathing deeply, trying to calm himself down.

"First time knotting can be intense." Dazai breathed, as he allowed one hand to go to Atsushi's hair and run through the sweaty locks, comforting him even though he also seemed quite a bit affected by this situation.

Atsushi pulled himself together as best as he could and tried to recall what the many alpha protagonists did in those erotic romance novels he read, once they knotted their partner.

Then, he gently gripped Osamu's body, and turned it to the side, as he nuzzled behind him, breathing in deeply and kissing his shoulder.

The brunet let out a soft chuckle, as they laid there, under the covers, their hearts beating out of their chests.

"God, it's so much," Dazai sighed from behind him, grabbing his hand and pulling his wrist closer to his lips, trying to breathe in every drop of pheromones oozing off of Atsushi's trembling body.

"First timers are always, such a handful." The man breathed out, as Atsushi continued to orgasm, his knot not calming down, not letting up, even as overstimulation kicked in.

It was both the most painful and yet pleasurable thing he's ever experienced and it was driving him insane, as he continued to scent mark Osamu subconsciously.

"I'm sorry," He said back, as he glanced at the man apologetically, getting a small little look in turn as Osamu gripped his hand.

"No, I'm sorry. I…made you do this. You should've let me take my suppressants." The man mumbled, still somewhat bothered by the fact that Atsushi didn't let him take his suppressants.

Did he hate this that much? Atsushi frowned, feeling dejected for whatever reason.  

"Giving out your first time to a suicidal maniac is a bad life desicion." Dazai disclosed, which made him stare in realization.

It wasn't that Dazai hated this that much. It was that he thought that he wasn't suited to be Atsushi's first time. That he hated the fact that the tiger had to "settle" for him.

And whilst this didn't happen under the best circumstances, it also didn't feel…terrible.

It felt…good. He wanted to say as much. Osamu was truly handsome, patient, and even though he hated their instincts the fact that their bodies mostly moved on their own helped him a lot and so did the fact that Dazai took his time to both prepare himself and that he had genuine experience in this field to keep both of them calm with his pheromones.

"You'll come to regret it." He hated it. Hated the clear self resentment and the fact that Osamu was putting himself down. 

Dazai, although suicidal, was also extremely confident usually. So seeing this side of him was strange. It tugged on his heart strings and played him like the saddest little violin. He hated how this was probably how Dazai actually felt about himself.

The brunet seemed like he thought of himself as nothing but a being made to die. Somebody who wasn't worth a lot, a terrible person who only deserved other terrible people and somebody who's sinned beyond redemption.

That's what made Atsushi always so concerned about him. The way he'd treat himself, with no care, made him want to take care of him. But Atsushi knew that Dazai would never let that happen.

"Stop that. I can smell whenever you get inside of that head of yours. We're mated now." The brunet rolled his eyes, as he turned in Atsushi's grasp, making them both gasp and shiver.

Atsushi assisted the man in his endeavour and helped him turn around, with Dazai putting one of his legs around Atsushi's waist again, to make the position easier on their bodies.

"I'm…Dazai-san, I'm not disappointed that you were my first. I just don't like the circumstances." He tried, gently stroking the man's skin and feeling his knot moving inside the brunet through his stomach. 

That made the brunet in his hold freeze.

Before the man looked at him. 

"You…don't tell me you like me." The man said, quietly, staring at him with a look that made him question why the brunet seemed to look both like he just heard the best and yet the worst news of his life.

He couldn't tell what his feelings were for the man before this. He found Dazai charismatic, funny, although a bit insane, but most definitely had a boyish little crush on how handsome the man was. He wasn't sure that he liked him, but he did wonder how the brunet felt about him .

And so, he asked.

"Why?" 

A silent little second passed between them. Before the brunet looked away, unable to answer him.

Although puzzled and confused by the man, he accepted silence as an answer and simply continued to gently stroke his skin, as they laid there, waiting for his knot to calm down.

He could feel the first signs of his rut. And they were rough.

First came the undeniable surge of lust, but luckily he didn't have the usual pain nor irritation, due to the fact that he was inside of…his mate, so he was at the very least grateful for that. Since they were already knotted, he simply rutted up into the brunet and felt him clamp around him, probably releasing pheromones in the air that he couldn't smell, but ones that made Osamu whine in his hold nonetheless.

"What do I smell like?" He asked, trying to avert from the awkward theme beforehand, getting a hazy look in turn.

"Lavender." Huh. That was odd. He usually read that alphas smelled more woodsy, rather than floral.

"It smells really good." The brunet mumbled, as he sniffed his neck again and made the young alpha shiver.

"You smell like roses." Atsushi muttered back, as he took a deep breath and leaned into the touch, feeling Osamu nibble against his skin, as his rut picked up, his body still unconsciously moving even as his knot deflated.

"Roses? Most just say flowery." Dazai recalled, as he traced his fingers through Atsushi's hair again, releasing more pheromones in the air.

His control over his pheromones during his heat was amazing. The scent of rain from before must've been his distressed ones and the fact that he had enough control to not only stop it from emitting but to also emit calming ones through his hazy state during their mutual moment of intimacy, was nothing short of impressive.

"Yeah, it's floral, but it also has a specific essence of rose." The tiger mumbled, as he hugged Osamu closer, mind a bit cloudy.

"When I smell it, I picture a burgundy rose, in autumn bloom."

Dazai smiled against his throat and ground down against him, his body responding to Atsushi's own scent and state.

"That's awfully romantic, Atsushi-kun." He rolled his eyes, as he pulled back and moved atop the boy, making Atsushi gasp in surprise at the sudden switch of positions.

"But I'm afraid my imagination is not as good as yours." The brunet mumbled, as he pulled the blanket around himself, hiding their private area, mostly for Atsushi's sake, who was extremely embarrassed in this position, as he panted below the omega and gripped his hips.

"I'll try it, anyways." Dazai hummed thoughtfully, making Atsushi whine as the man closed his eyes and circled his hips.

He was doing this because of the fact that Atsushi was going through his rut. He was going to take charge and help him out. God, Atsushi felt like Osamu was way kinder than he let on.

"I can just kinda see a lavender popping out of the grass in a field." The brunet sighed, slowly opening his eyes back up and trailing them over Atsushi's sweaty, tense body.

"You need to relax." Dazai mumbled, trailing his hands over Atsushi's chest, as his shirt slipped down his shoulder, revealing more of his soft, milky skin, that Atsushi wanted to lean up and bite, lick, cover in hickies and bites, make his.

His head was spinning and his entire body felt powerless against his own restraints, as he willed himself in place, feeling more and more like he might lose control, this time utterly and completely so.

"We'll see each other naked many times." Osamu reminded, as he moved up and down by now, with Atsushi's nails digging into his thighs, as the boy desperately gasped for air.

Osamu felt so good. So, so good. His body was made for it, made for him.

"Especially now that your rut is kicking up." The voice brought him out of his state and made him want to punch himself for the thoughts, as if he could control them.

"God, you're going to be absolutely feral as soon as you lose control." The brunet muttered, still slowly grinding down on him, which was the only thing keeping him as conscious as he was at the moment. He wondered. How the hell did Dazai control himself so well, even during heat?

Heats were twice as hard as ruts, when it came down to control, so how did he manage to stay so coherent this entire time?

"I need you to understand that alphas can get violent during ruts and that heats make it easy for the omega to not only go through that but to also enjoy it." The man said, as he leaned down closer to Atsushi, inches between their lips, hips still circling slowly, going up and down enough to keep him wanting yet not nearly enough to satiate the beast. "So don't feel like a kicked puppy, once you come to your senses."

That made him bite his lip wearily.

"I might be bloody, bruised and covered in hickies and bites."

The last thing he wanted was for Dazai to be in pain during this or even after.

"You're an alpha. You cannot control what you do during rut." The omega let out breathily, as he gripped his hips and began helping him with the pace, making him speed up, because his whole body felt like it might burst if they didnt start fucking properly.

"You're gonna want to mark your territory and make sure I look claimed." Look claimed. Is that why his brain was screaming at him to lean up and bite Osamu again?

Was that why, when he stared at the pale flesh, his brain became mush and his teeth ached to sink into it?

"And I'm going to enjoy it because I'm an omega."

Their dynamics did make him sick, but he couldn't help but want to do it. Because right now, both of them needed it. Needed to feel each other. 

He only gripped Osamu's hips harsher and ground up into him as hard as he could from this angle, pulling him almost entirely off his cock before he dropped the man down on it again and drew a moan out of the red lips that he needed to kiss.

"I'll want you to be as possessive of me as possible and I'll take pride in the fact that my alpha wants everyone to know that I'm his." God, Atsushi's head was spinning as he laid there, and began bouncing Dazai on his cock, and even breathing was hard.

He moved before he even knew it, and manhandled Dazai onto his back, as he felt the overwhelming urge to fuck the omega into the sheets.

It hurt. His entire being was screaming at him to breed the brunet properly, to lift his hips up and make sure that his cum would stay where it needed to be, his body and mind was telling him that he should lean down and take Osamu's breath away with his lips, mark every part of him until he smelled and looked like he was properly claimed, and it was driving him insane.

"Dazai-san," He gasped, as he began fucking into the brunet harshly, leaning down and kissing his cheek apologetically, purposefully avoiding his lips, knowing that he wasn't allowed to kiss the man.

"I'm sorry, it just, I can't," The boy tried to explain, but he could barely think, let alone talk.

"It's fine. Atsushi-kun, it's fuck, " The bruent tried to comfort him, but Atsushi interrupted him, as he ground up against the brunet's g-spot and grabbed his cock, jerking him off in time with the thrusts and making the brunet literally choke on his spit.

" Oh fuck, " Osamu let out, as he cradled Atsushi closer and spread his legs, grinding down into it again, brown eyes tearing up, making Atsushi lean down and kiss the corners, as his free hand travelled up the bare skin.

God his mind was fuzzy.

"Smells so good, you smell so good," He began, dryly, as he leaned down and licked the brunet's throat, feeling his omega shudder under him and hearing him mewl at the praise.

"And you feel so good. Perfect." He mumbled again, ranting needlessly, as his pace sped up even more, wet sounds filling his ears as he moved, feeling Dazai's cock jerk in his hand and pulse every time he ground deeply inside and imprinted himself, molded his omega after his shape.

"God, you're handsome Dazai-san." Atsushi whined as he stared at the man like he wanted to eat him alive.

The beast inside of him sure did want that. 

"Stop being so embarrassing," The flustered brunet muttered, but still couldn't help but rut against his harsh thrusts, and tighten at his praises as their pheromones mixed and mangled, while they scented each other, wanting to rub every inch of their skin together. 

He couldn't stay conscious enough at one point. His instincts completely took over and he found himself biting into the claiming mark on Dazai's neck again, then licking up the blood and kissing the sensitive gland, as he inhaled deeply.

" Atsushi, " Dazai groaned in his embrace, as he got railed against the sheets, small little moans getting punched out of his lithe, tall body each time that Atsushi fucked inside.

"Omega, my, my omega, " He got out, growled, like an animal, as his pace got brutal, switching the angle so that he was pistoning in and out as fast, as deep as he could.

Fucking his cum so far inside that he wasn't sure that Dazai could ever get it out. They'd smell of each other for weeks, and that thought only left him even more turned on, as he pulled back from the beautiful throat and admired his bite, seeing how prettily it sat atop the porcelain, sensitive skin.

He pulled the brunet's thigh closer, and kissed the inner section, as he threw Dazai's legs on his shoulders, using this angle to brush deeper inside of the sensitive walls, seeing himself move inside of Dazai's stomach, which made him almost knot the man on the spot again.

He jerked the brunet off with more vigour by now, which drew a loud scream out of the omega and made him seize as he orgasmed again, tears sliding down his face as he got fucked right through it, with Atsushi only speeding up, pleased that he made his omega feel good again.

Dazai squirted more slick around his cock, making him bite down on his lip as the man tried to hide his face again, making Atsushi pin his wrists to the headboard, which drew a hesitant surprised gasp out of his mate.

"Wanna see you." He got out, as he continued to fuck the man hard and fast, seeing his mate cry out so prettily and nicely for him, eyes rolling in the back of his head as Atsushi continued to jerk him off and fuck him all at once.

The tiger leaned down again and began biting every spot that he could reach, continued to suck on them till he drew blood to the surface of the skin and watched as it darkened to red and then finally purple, littering every little place that he could find in his touch.

He went down even to Dazai's chest, kissed his pecs, bit his nipple hard enough to bleed, and then soothed it over with his tongue, feeling it harden between his lips, before he sucked on it, which made the brunet groan and arch into his touch.

He could feel Osamu's beating heart as he continued to sickle on the flesh, run it between his teeth and then suck again, leaving spit and red on it as he finally pulled back to stare at his handy work.

God. 

Fuck.

Osamu looked beautiful.

His chest, his neck, even his shoulders were covered in Atsushi's teeth, in his hickies, and his nails left deep marks themselves inside of Atsushi's skin, which made the alpha very pleased that his omega was also marking him.

The tiger leaned down again, to the other nipple, gave it the same treatment, flicked the hard nip with his tongue and then teased it with his teeth, pulled the sensitive flesh up and then released it, before he leaned down again and sucked it, feeling Dazai tighten even more around him, as he thumbed the tip of the weeping cock in his hand, the cum from before being used as lube to jerk the man through another orgasm that made his mate melt and shiver in his hold, unmoving by now from the sheer exhaustion of it all.

"I'm gonna breed you so well," He found himself saying, pulling back from the brunet's chest, as his haze only continued to grow, by now barely anything of his rationality left, only the need to make the brunet full, to shove inside as deep as he could, to make sure his knot would leave the man filled to the brim with his seed, dripping.

He stared down at the hard nipples and pinched one with his free hand, twisted it, felt his saliva with his fingers, before he released it and began circling it, in the same way that he was circling the tip of Dazai's cock.

"Alpha," Osamu called, making him purr darkly and pull his omega closer, staring into those warm, dark brown eyes.

"Alpha, alpha, please, I want you to knot me." The brunet gasped, babbled, finally giving into his instincts, crying for it so prettily, so needily, that the young alpha felt like he needed to do it.

He picked up the pace even more, rocking the bed, their sweaty, needy bodies only growing even hotter with each and every thrust, with Osamu's insides clinging onto him, trying to milk him, begging for his cum, and it was impossible not to give in and lean down, claim his lips with his own as he knotted the brunet and locked them in place again, groaning as Dazai came with him.

Only this time, that didn't stop him.

The young alpha continued to rock into the body below him, overstimulating Osamu so much that the omega began sobbing out of both pleasure and pain as they pulled back, saliva trailing down his chin as he gushed slick around his cock, making the tiger touch the place where they were connected and scoop up some of that delicious smelling slick to his lips.

It smelled like a five star meal. Like something that he couldn't get enough of.

And so, he licked his fingers clean, as he stared at his mate and continued to fuck him, to breed him, to make sure his cum was deep enough, far enough to please the omega.

" Alpha !" Osamu cried again, his arms clinging to Atsushi all of a sudden and pulling him closer, hips unable to decide if they wanted to escape the sensation or fuck down onto it as Atsushi's pace sped up.

"Too, too much, holy," Dazai got out, slowly coming down from his heat induced high due to the fact that the young alpha had knotted him, but the tiger was far from back from his own headspace, as he continued to take Osamu apart in every way possible, even as the man came again, twitching in his hold.

He began speeding up again, fucking his omega as hard as he could with the knot in place, which caused a rather uncomfortable reaction from the brunet as he tried to pull back, but he couldn't let the omega hurt himself so he held those curvy hips in place,

" Atsushi, " The brunet called out, making him finally somehow snap out of it at the genuine uncomfortableness in Osamu's voice and will his body into place.

"You made me cum five times. Five times." Osamu panted, trying to catch his breath, thighs shaking, fingers weakly twitching from where his wrists were still pinned. "Slow down, even heat doesn't make my recovery as fast as yours, you beast." The brunet mumbled, making him release the bruised wrists and stare down apologetically.

"How come you have this much stamina? I mean even for an eighteen year old that is just ridiculous! " Osamu whined, and by the looks of it, he didn't seem…mad. He seemed like he was….considering this as sort of a competition between them, on who has more stamina and that made the tiger blink, before he laughed.

That was such a Dazai thing to do. Turn every bad situation into a game or a joke. 

"Why are you laughing during sex? I'm the one clinically insane here." The brunet rolled his eyes, as the tiger fell atop his body and laid there, still chuckling.

"It's just….you're still as normal as ever." 

The brunet paused a bit. Before he too, chuckled.

"I mean, what can you do, am I right?" He shrugged from under Atsushi, as the boy pulled out, their heat and rut seemingly satiated for a bit.

"We need to grab something to eat while we're not so horny that we can't stop fucking like rabbits." The vulgarness had him pretty stunned. "I'm pretty sure I have noodles." And yet, the contrast between it and Dazai's last sentence drew another laugh out of him, as he laid there.

"You're too giggly. I'm going to punch you in the dick." Dazai rolled his eyes at him, which only made him giggle again. He didn't know why, but he felt like…getting it out of their system really cleared his mind.

Their relationship, after having to fuck each other didn't really…change all that much. Dazai, although a bit less pleased with him than before, due to his current reactions, was still as sassy, as snarky and as demanding as ever. 

And that was good. His biggest fear in this situation was losing his friend. But that didn't seem to be the case.

"I'm gonna go make us noodles." The boy smiled, beamed, from his side of the bed, leaving a puzzled, perplexed and confused omega to lay in it, as he went to the kitchen.

And Dazai was truly left to wonder, which one of them actually lacked sanity.

And as they ate after, and drank some water for their sore throats, they spent that time talking about their issues.

"I don't want you to kill yourself and I'll stop you from doing it." The tiger explained, as he swallowed, and wiped his lips, with both of them sitting on the bed with their legs crossed, feeling better than before, so much so that they even put their underwear on.

"Even if that means you'll be stuck with me as your permanent mate? That's stupid." The brunet shrugged, but there was something more that he wanted to say, clearly, by the slight smell of what he figured was distress in the air.

"It might be. But…you matter to me. As a mentor, as a coworker…as a friend and…I just don't want to lose you, Dazai-san."

The room was silent after his confession.

It felt like the quietness was almost too loud.

Until they looked at each other.

"Caring for the dead man walking will only put you into an early grave." 

"So, dig two graves." Atsushi glared, equally as serious about his own statement.

"Never took you as a double suicide kind of guy, but them again, I am intrigued. Maybe we should do it." Dazai joked, in his usual fashion. "Mates, killing themselves after their first heat and rut spent together. The most romantic ending to a first date ever." Osamu giggled, making him roll his eyes.

"Dazai-san I'm not killing myself and neither are you." He muttered, as he took a sip of water and watched Dazai's face carefully.

"I'm just saying that I'm going to make sure you're alive and well." The tiger sighed, as he grabbed Dazai's hand, feeling the man almost pull back in surprise.

"I've lost everything and I'm not losing you. Any of you." 

The brown eyes softened.

"I understand that. But I've never even been alive in the first place. Some people are just born to die." He tried explaining. 

"I'll just keep on resuscitating you until your heart beats by itself." Atsushi mumbled back, as he stared at the man.

"I call code DNR." 

And then, he laughed. Because even though the joke was messed up, and he was trying to have a serious conversation, he couldn't deny the fact that he found Dazai funny. Funny, handsome, well spoken, smart, batshit crazy, soft, beautiful, kind and so, so maddeningly under-appreciative of himself.

"I'm serious. We can make this work." He found himself muttering, which made the omega avert his gaze.

"I'm not too sure of that myself. Don't expect romance out of me." The man sighed, which made him squeeze his hand again.

"And I don't. I just want us both to not suffer." He whispered, as he, this time, averted his gaze.

"If you don't like me in that way, we can just spend heats and ruts together and have lovers on the side." The brunet released more pheromones, ones that were probably confusion, if the puzzled expression on his face was anything to go by. 

Learning about Dazai like this was…quite the feeling. 

Their bond might've been a rushed decision due to their circumstances but…it brought along a string of opportunities.

Maybe he could finally tell what the hell the man was thinking and read him better, perhaps even out of heat.

"I just…we had to do it. I don't want you to feel like you've forced me to tie myself to you. I would do it again, even if I could turn back time." The tiger finally finished his rant, which made Dazai look back at him.

"It's not a matter of me not seeing you in that way." The brunet sighed, as he pulled his hand back from Atsushi's and waved it around to try and explain himself.

"You're attractive." That, of all things that they did that day, was what made him the most flustered. Beetroot-red even.

"I just don't feel right with it. We are two different worlds. I'm not the one for you." 

He frowned.

"I don't like that. The way you're trying to pin this as you protecting me from yourself." The tiger said, as he stared at the man intently. 

"But," The brunet tried, but he interrupted.

"Dazai-san." 

That made Dazai stop for a second and look at him.

"Hear me out for a bit, please. I'm not naive." The tiger sighed as he grasped his own hands together and took a deep breath. Putting his emotions into words was always difficult.

But he wanted to at the very least try.  

"You've worked with the mafia before. And you're someone dangerous. That much is clear." The brown eyes glanced at him, as if Dazai was proud of his realization. He knew as much by the reaction of both Mori, when they first met the man and even by the people's behaviour in the mafia. He knew it the first time he saw Akutagawa and Dazai interact.

"You might've not been a good person in the past and you might not be perfect now either but…" 

Dazai looked hooked onto his every word, as the tiger carried on. 

"You are still not unredeemable, nor a monster. I care about you." He could see those brown eyes analyse his face, search for a lie, but.

They couldn't possibly find it. Because he was being nothing short of honest.

"No matter your past, your behaviour, I just… I care. I want to care." Dazai's breath hitched.

"Even before this bond, I'd do your reports, I'd save you from your dumb attempts and I'd even take on your missions." He tried to explain, because the last thing Atsushi wanted right now was for the man to think that this sudden, rushed thing between them was what made Atsushi care so deeply for the brunet.

"You've helped me in the past. And now, I want to help you." He admitted, under his breath.

"I can't make you accept me, but since we found ourselves in this situation, why don't we….make the best of it?" There was hope in his voice, hope on his face and his eyes shined brightly, as he tried to convince the man to at the very least take this chance.

"You sly little cat." The man sighed, before reaching out and running his thumb across Atsushi's face. "Y'know what, fine, Atsushi-kun." The tiger let go of a breath that he didn't know he was holding.

"If you want us to try this, why not." Osamu shrugged, as he leaned closer.

"Just make sure that you have more guts and claws in the sheets, kitty." He could barely contain his shiver, as he felt the man breathe on his lips.

"Because if my feeling is correct, I'm about to pounce on you at any moment."  The brunet smiled, before he kissed him, making Atsushi gasp in surprise, and yet still pull the brunet into his lap, arms intertwining around Osamu's waist, pulling him closer.

Maybe they didn't love each other yet. Maybe they were forced into this bond.

But that didn't mean that they couldn't learn to enjoy one another, and perhaps…

Maybe their care might morph into something more, one day.
