Bakugou Katsuki — »roommates«

You and Katsuki were in the same class, Class 1-A, but you'd never exchanged a single word. You were quieter, always distant from others and rarely spoke, as you didn't like being the center of attention or causing trouble. That's why you didn't hang out with Bakugou, since you found him too loud and shouty.

Now, everyone had an assigned dorm room, in pairs. Aizawa had paired everyone up, and unfortunately, you ended up as Bakugou's roommate. You obviously complained, trying to change partners, but Aizawa simply wouldn't budge.

And so it began. Now, they were both standing in front of the door to their new dorm room. Bakugou, of course, gently pushed past you to get inside first.
