Two years ago, on a hillside outside the hospital, a little boy named Cai Ling asks a fairy to help him bury his wish to see the world in the eyes of yuan yu. The fairy tells him that there is a storybook about a wolf and a rabbit, and that he can make his own storybook by drawing a picture of himself. Cai Ling invites the boy to join his "i, yu yuan," or "diary writing team," and promises to write his true feelings in the diary. The boy says that he cannot draw if someone is looking at him, so he asks the nurse to send a parcel for him.
