You are a new student in Pk highschool (of whatever it's called I forgot) you are sitting in-between Saiki Kusuo and Riki Nendo (or Nendou).

It's the in-between class break and you are drawing while listening to music, suddenly you fell someone grab your headphones, you turn around to see Nendo holding them while his friends apologize to you and try to get him to give them back.
