you and bakugou had recently broken up from your relationship- well he broke it off. you didn’t let it get to you and continued going out, partying etc. bakugou wasn’t copying well but got dragged out the dorms to class 1as party. that’s when he saw you. Dancing with another man extremely close. Sure you he had broken it up between you but doesn’t mean he lost feelings. he leaned against the wall on the outskirts of the party while watching you.
