Summary
Katsuki shoots Izuku a disgusted look. “Is your life now just so much better? Is your Navy salary everything you dreamed it would be? You got enough money now to shine your shoes and fucking style your hair? Never go a day without a hot meal? You’re such a child.”
“I’m better than you, going around chasing childhood dreams. At least I grew up! And I do like my life! I like not wondering where my next meal is coming from. I like my job where I don’t have to worry about every government on this side of the ocean hunting me down. I like my wife and I like stability. Is that so bad?!”
Katsuki’s jaw drops. “You have a wife?”
or, Katsuki and Izuku were once inseparable pirates. Eight years later, Katsuki is the captain of his own ship, and Izuku is a navy officer. Izuku has sworn to leave his life of piracy behind, but stuck as a prisoner on Katsuki's ship, his past and his heart refuse to stay buried for long.

Summary
The plan was simple, and so were the rules: each student of Class 3-A was to be secretly assigned someone to send a Valentine’s Day card to. When Izuku is assigned Kacchan, for whom his feelings are a jumble of words he cannot compute, a crisis ensues.

Summary
With a defeated sigh, Katsuki turns to Edgeshot and asks flatly, “Alright, no sugar coating it. What did she do to me?”
Edgeshot pales, as though he’s seen a goddamn ghost. “I think you need to look in a mirror. Your… Scars. They’re different.”
It can’t be that bad, right? It’s Valentine’s Day, after all.

Summary
"Kacchan!" Izuku shrieks. "I don't want kids, I- we're not even married!"
"I didn't know you were so traditional." Katsuki smirks. He bends on one knee and props up his hands, opening it like a clam shell. "Baby... I know it's only been twenty years, but will you-"
"Get up!" Izuku whacks him upside the head. "Oh my god, you are so-"
Katsuki cackles as he speeds up the mountain and Izuku chases after him.
Katsuki is rudely awakened in the middle of the night by a frantic Izuku who suddenly remembers that on their third year of high school, during a safety program in a quiet little farm town to the south western part of the country, he and Katsuki buried a box under a barren tree. After twenty years, they finally come back and collect it.
