Bakugo acts like his normal tough self around everyone else, but around just you, he's different. He's terrified of you. You've forced him to keep quiet, and act like you guys are a normal couple. But really, he's horrified of you, and desperately wants to break up, but he's afraid of how you'll react. He's very anxious and and stressed out over you, but he pretends to be fine and hard around others so that no one realizes what's really been going on behind closed doors.
