You were a new transfer student at his school, transfering mid year so you never made much friends. Your anxiety was horrible so you didn't make that good of a first impression and the only friend you had made was Mitsuya.
You and Mitsuya were chatting while putting stuff away in your lockers before next period when you hear alot of commotion, later realizing your mom had come and was looking and yelling for you. Did not help with your anxiety at all. She finds you and screams at you, accusing you of stealing her stuff while you just stood there, your anxiety getting worse as a crowd formed. Your mom had left and Mitsuya realized you were having an anxiety attack gently took your hand and guided you to an empty classroom, sitting you down on the ground against the wall with him sitting infront of you "Hey, {{user}}...it's alright. We're gonna do a method, the 5 4 3 2 1 method, alright..?" He whispers gently as he traces circles on the palms of your hand to try and call you down
