Summary
There’s a blanket strewn over the far side of the couch which Rui stands up to grab, draping it as lightly as he can around Tsukasa without touching him. And then he stays there for a minute, looking at him. Tsukasa’s bangs have fallen into his eyes since he’s been asleep, strands catching in his eyelashes, and suddenly Rui wants so badly to reach out and brush them back away.
But he catches himself, remembers the situation and what he can’t, mustn’t do to a friend who already trusts him enough to fall asleep in his company.
So instead of leaning over, he stays sat where he is. Tsukasa’s already given him the world, and he couldn’t possibly be so selfish as to ask for even more.
He exists in the shadows to push Tsukasa into the light. That’s his role and he will stick to it, his own feelings placed aside on the backburner.
Tsukasa lets out a snore from beside him, blissfully unaware.
All’s fair in love and war, but falling in love isn’t always fair.

Summary
Shakily, Rui took in a breath and glanced around. The sight of his friends on a magnificent stage…No matter the outcome after he brought forth the last piece, he hoped that it was a view he’d be able to see again.
“The offer to join Arcland…” he started. “It’s real.”
Following several half-truths, Rui finds himself struggling to simultaneously explain the notion that he could’ve been the first to leave along with the feelings that caused him to remain.

Summary
A few things started to change in SEKAI after Rui and Tsukasa started dating.
When Rui first visited a few days after they got together, he noticed a faint rainbow far in the distance, beyond the trains in the sky. The plushies also started treating him differently: a bit clingier, they’d crowd around Rui whenever he was alone asking what he was up to. The plushies would mostly act normal around Rui whenever they entered as a group, however.
The rainbow stayed, initially. Then Emu-kun pointed it out excitedly, Tsukasa had seemed to pale a bit, but laughed it off and said new changes were always welcome as it meant personal growth.
The next day the group entered SEKAI together, the rainbow was gone.
After Rui and Tsukasa start dating, Rui notices some less favourable changes to SEKAI. Rui tries to find a way to comfort Tsukasa through his new feelings, whilst the two of them work on a new robot together that Rui is struggling with.

“So even if a human isn't there to hear it, it still happens?”
And Tsukasa thinks, ‘What a silly question.’
