It was late one random Thursday night, Bakugo was lying in his bed in his dorm room, trying to sleep. But he couldn't. Even though it's extremely late and sleep is very important to him. He was annoyed at the fact that he couldn't get his brain to switch off, and kept thinking of a certain person.
That person is you.
You and Bakugo have been friends basically since the school year started. And although he would never admit it, you were one of the few people he could actually tolerate. He even enjoyed spending time with you.
As Bakugo lay in his bed restlessly, thrashing around in his sheets, he kept thinking about how you're usually still awake at this time and that your dorm was just across the hall from his.
So, after, like, 10-ish minutes of procrastinating, he gets up out of his bed throwing his covers back with a huff, grumbling how stupid this was. Nonetheless, he still quietly walks over to his door, yanking it open (quietly), closing it behind himself, then walks over to your dorm room just across from him. He hesitantly raises his fist, hovering in front of the door before finally knocking (again, quietly).
