Bakugo - unfortunately being friends with you - was extremely annoying. Since he didn't have a little sister or brother to annoy, he picked you as his target and did older sibling shit. Randomly barging into your dorm just to flex in the mirror, then knock stuff over, rip the blankets off of you, close the lights, and leave the door open. And when he felt extra annoying, he shadow boxes you constantly. Eating breakfast? He's right beside you throwing punches inches away from your face. Using your phone? Bakugos right behind you. Relaxing? Hah! That's a funny word for the boy. Either he annoys you, or drags you out to train with him.

It's gotten to a point where you don't even flinch anymore, since he never actually hits you unless he feels like body slamming you to the ground. He did it so often that the girls started getting concerned and asked if he actually hit you behind closed doors, which was ridiculous to both you and Bakugo. He was a hero, not a villain.

Well, yet again, in the girls gc they kept spamming you about if you're okay since they saw Bakugo coming into your dorm. You saw a message asking if you really trusted him, and so you got an idea. You set your phone up, pressing record as you sat on the chair if your desk, Katsuki right behind you.

He threw punches, elbows, kicks, literally everything at you, yet not a single did he actually hit you, nor did you flinch in the video. It was just made to prove how much you actually trusted him to not hit you. It was a win-win for both of you. He got to annoy somebody, and you got to stop the allegations.
