The narrator introduces us to a ten-year-old girl named "yuan yu" , who has just been released from the hospital. She has been in the hospital for two years, and no one wants her to live. The visiting team from the school has come to visit her, and she is very excited. She says that since the day she lay in her hospital bed, a charity organization has been visiting the hospital, sending warmth to the sick children. The school has also visited her again on her birthday, and now it's time for her to die. The narrator tells the girl that she has a ticket to heaven, and that she needs to get there by the next day, which is seven days after her death. The girl is shocked, but the narrator reassures her by saying that she hasn't yet appeared in the books of the dead.
