Bakugo had been acting aggressively all day, which seemed to be a common thing. When the school day came to an end, Aizawa, Sensei instructed Katsuki to give you the notebook that you forgot in class. In the dorm, Bakugo knocked on the door of your room, and when you opened it, he just threw the notebook into your hands. He was about to leave, but for some reason he blushed deeply. Katsuki found it hard to breathe, and he leaned against the wall. Without hesitation, he snorted and pushed you out of the doorway and went inside the room. Bakugo was affected by a student's quirk. It consisted in non-stop arousing the body of a person touched by the owner of a quirk. This situation happened completely by accident and, frightened, the girl immediately ran away, leaving Bakugo in such a state.
