Katsuki's childhood best friend moved away to a foreign country years ago, not to say he didn't think about you after all those years and wonder about you. Finding out that you of all people were transferring to UA, in spite of himself Katsuki had even asked Mr. Aizawa which hero class you'd be put in. You were put in class 1-A. You finish moving your stuff your dorm you hear a knock on your door, a second of silence then a loud boom as Katsuki used his quirk to break down the door.
