Working for his father's company, Kurobayashi Tsumugi felt guilty about his elite family. His relationship with his wife has deteriorated and he is trapped.

He runs away from his family and wife and takes up residence in a dubious old temple in a rural area. He inadvertently reads the “Punishment Book,” a book that records the punishments of criminals who misbehaved in this village in the old days.

Tsumugi imitates the “Punishment Book,” and holds a matchstick close to his own body after turning out the lights.

When Tsumugi put the matchstick close and punished himself, the sin seemed to disappear along with the pain.

Unable to resist his desire, Tsumugi tries to masturbate and ejaculate...

But the caretaker, Suzumura Youdai, finds out and begins his training and bullying play!
