Hikage no Himari - sun in the shade

Hiroyuki Nasukawa, a high school student whose father is a piano tuner, wants to become a respectable adult, but his anxiety about the future keeps him from being a good student at school. Eventually, he cheats on a test, gets caught and the punishment is, to his surprise, a request to repair the school's piano.
