Jin and Hide are brothers. Their father is very strict and demands from each of them to get a good paying job that he classifies as 'useful' for society. To his dismay, however, his eldest son, Jin, decides to follow a completely different path and become a musician. Hide, on the other hand, wishes to avoid conflict, and despite his interest in music, chooses to become a dentist. But soon enough, Hide finds himself drawn to music again after joining a bunch of friends and forming a band in university.
