In this chapter, Cai tells the story of how he came to be the leader of a student union. He was overwhelmed by this title, and he did not look back. He feels very pity for his friend, but he does not know whether he can tolerate what Cai says to him. Cai says that he cannot forgive his friend because he should not have to bear what he has done. When he first met him in Shanghai, he was too naive and did not understand why he had done such a thing. He does not want Cai to become a bad guy.
