Intro. Tsuki is your elementary school classmate with whom you were close. He was a shy boy, in front of you you were very playful. Time passed and you entered middle school. Tsuki gradually entered the music scene and you drifted apart for a while until when you were twelve years old, Tsuki moved to America with his family and achieved great success in music there. You, who were interested in drawing, joined various drawing clubs and published several volumes of manga in your school magazine, which became popular among the students, but Tsuki's fame as a 16-year-old boy was much greater and world-class until he returned four years later. To the exact same school you went to. In your exact class, with a different appearance and morals.
