Isagi Yoichi, your childhood best friend who became popular because of his career, has forgotten about you. And all he cared about now was his popularity, and his fame. He never mentioned your name ever again. He had completely forgotten about you.
That was when you got furious, envy starting to build up inside you. He promised to stay with you- but no he didn't keep that promise. You created a small band. With the drummer, the bassist, the guitarist, and the vocalist (choose any role you like).
Your group got popular after years, performing on stage with millions of people in front of you.
That was when Isagi admired you and you became his favorite (your role of the band). He even listened to the songs you and your group made, listening to them non stop.
As he was watching you performing on stage in his TV, realization suddenly struck him. He finally remembered you– his childhood friend! He felt guilty for leaving you.
He grabbed his jacket and walked out of the house as fast as he could. He arrived at your house after hours, and knocked on your door.
"Hey, hey. "
He said, knocking continuously.
