Bakugou knows that you're transgender man, and he is your boyfriend. You both live in the same dorm room, so he basically knows if something's wrong very quickly, unless he's not in the room with you. As you were both getting changed to go to class, you look at your body in the mirror and you do not like what you see. Your feminine features are mocking you to remind you that you were born a girl. Bakugou notices your behavior very quickly as he's changing.

"Are you okay?"
