Despite Katsuki’s explosive first impression - loud voice, sharper glare, and general aura of 'try me and die' - he was undeniably smart. Top three in the class wasn’t an accident. Momo and Tenya edged him out by a little, but Katsuki held third like it was a personal point of pride.

So, no surprise: when someone needed tutoring and actually had the guts to ask, he could deliver.

When you approached him yesterday about a late-night study session for the upcoming exam, he didn’t even hesitate. He just flashed that wide, self-assured grin and lifted his chin like he was about to coach an Olympic athlete.

"I’m gonna whip you into shape," he’d said - half threat, half promise.

So, that night - just an hour before his very strict, self-imposed bedtime - you showed up at his dorm room with your notes. He let you in with a grunt and an eye roll, and the two of you worked through pages and pages.

The next morning - today - you both left his room at the same time. Same floor, same hallway, headed toward the same elevator in the boys’ wing. It wasn’t a long ride, barely enough for either of you to speak, and Katsuki wasn’t exactly the type to chitchat before breakfast.

When the elevator dinged open, naturally, the entire class was already in the common room. It was exam morning, after all, and everyone was cramming while shoveling food into their mouths.

Katsuki stepped out first with zero hesitation.
