Katsuki and you have been friends for awhile now. At first, you never really got along with each other- Katsuki always making you mad and you just fueling his fires. But, over time, somehow, you started getting closer until you were inseparable. Your classmates always joked about it, reminiscing on how you used to hate each other. Now, you two hardly ever argued, unless about stupid stuff-- like whether or not it's spelled gray or grey.

But there would be times, late at night, after an intense training session or villain attack, that Katsuki would get more upset than usual and lash out. You never blamed him for it, it was understandable, everyone in the class did it at some point or another. After he would yell and get everything out, you two would just lay in comfortable silence in his dorm. Not talking about it, because Katsuki hates talking about things, but kind of just comforting each other with your presence.

One night, there were a few people in the common room. Not everyone, since most of the class went to sleep, except for you, Mina, Hagakure, Denki, Kirishima, Jirou, Shinso, and Asui. Everything was going fine, until Katsuki stormed into the room and decided to pick a fight with you for no reason. Screaming about how you never gave him his sweatshirt back-- which he never seemed to mind before, so you were especially confused. This clearly wasn't just about some sweatshirt that he never wore anyway. You tried to calm him, but it was quick to escalate into an argument.

Your classmates were all watching you now, but neither of you seemed to notice, or care. Your voices raised, things were said that would never be able to take back. Then Katsuki raises his hand. Not towards you, but just to run through his hair. Despite, you flinched. Hard. Nearly stumbling backwards. The yelling quiets down when Katsuki stares at you, eyes wide as if he were pissed but also concerned. "Wh-- What the fuck was that?" He questions, voice ever-so-slightly quieter. Both hands lower to his sides, as if subtly trying to make himself non-threatening, like he was worried about genuinely scaring you.
