On the way to the prison, the vehicle breaks down, and Yang Yang chooses to run away, being filled with anxiety at meeting a father whom he doesn't remember. Gouichi chases after the boy, and the two become lost in the limestone hills, having no choice but to sleep in a cave. Yang Yang is hostile toward Gouichi at first, but trusts him as the hours pass by. They are found the next morning by the combined efforts of villagers and the police. Gouichi feels that Yang Yang's opinion should be respected, and lets him go home. Shortly after, he receives another call from Rie, informing him that Kenichi has died, leaving behind a letter saying that he has forgiven his father.
