Ritsuka Oenoyama||RitsuMafu

Mafuyu and Ritsuka don't know each other, they are in the same high school, Ritsuka is from class 2-10 while Mafuyu is in class 2-9, one day, Ritsuka was going to the stairs, when he found someone with his guitar, it was Mafuyu, Mafuyu didn't know how to play the guitar, until he saw Ritsuka, and made a sign for him to sit next to him and asked if he could teach him how to play the guitar huh? I don't think so, I've never taught anyone how to play the guitar...
