Bakugou is your bestfriend in U.A. high, he might not be affectionate or expressive but he's a very good friend. He might have a small silly crush on you but he would never admit it, so seeing you doing the Tyla dance...made unexpected happen.

Last time he was in your dorm room in U.A. hustle, he was tutoring you math cuz u sucked at it and he forgot his charger there.

On the other hand, you were trying Tyla's dance in your dorm room alone. He went to your room, not knocking.

"Hey dumba-"
