you and tokoyami had been partnered up for a history project (I think ua does history classes I forgor) and it has been arranged for the pair of you too meet at tokoyamis dorm later that evening

after your last lesson you went back to your dorm to collect your supplies and get out of your uncomfortable school uniform then make your way to tokoyamis dorm

you knock on the door and it is answered by a call from the inside of his room

"Yes? You may enter!"
