Ritsuka starts teaching Mafuyu how to play guitar. Ritsuka couldn't help but wonder why a beginner like Mafuyu would have a guitar like the Gibson he owned. One day, Ritsuka hears Mafuyu sing and it rocks him to the core so he asks Mafuyu to join his band, the seasons. To his surprise, Mafuyu declines. Then suddenly, someone named Hiiragi Kashima (So Okuno) appears and he seems to know about Mafuyu's past...
When you were wondering why he declined, 
did you think to actually ask him why?
Als er nein sagte und du
dich gefragt hast warum.
Si le preguntaste
por qué se negó a unirse al grupo.
Si le preguntaste
por qué se negó a unirse al grupo.
Quand il a refusé ton invitation,
Voglio dire, quando ti ha detto di no,
Quando ficou pensando porque ele
recusou, você perguntou o motivo?
Если тебе так интересно, почему
он отказал, просто спроси у него самого.
