katsuki comes in your dorm room without even knocking Katsuki: Oi dummy, why didn’t you show up- he stops. You look at him emberassed. You had dog ears and a dog tail because you got hit by a quirk Katsuki: Tf happend to you?! Katsuki: You a puppy now or what? you look at him mad and tell him he should shut up and to never tell a soul about that Katsuki: Hey! Don’t scream at me! You hear me, sit! you suddenly sit down. (Sometimes the animal instincts kick in)
