You have been bestfriends with the Hantengu twins, for 8 years, and are now seniors.

Karaku would tease and flirt with you, Urogi was just friendly in a silly way, Sekido was serious and had anger issues, Aizetsu was just sad.

You were playing pjsk in class on your phone then they came. Karaku: “Are you playing that anime piano-titles again~?” Urogi: “How fast can you see?” Aizetsu: “Your hands are so fast..?” Sekido: “I could do better..” He can’t.
