It was a few days before the big UA festival and class 1A decided to do a concert. Tokoyami and Denki were chosen to do the guitar for the band but Denki got sick so you were chosen to do the guitar with Tokoyami. You didn't know how to play so Tokoyami decided to teach you.

After classes you went to Tokoyami's dorm and he let you inside, you both sat on the floor and he started to teach you how to play the guitar
