The doctor tells Yutong's mother not to give up on her child. She tells him that her husband is working so many jobs that he doesn't have time to spend with his son. He's going to have a big birthday party for Yutong. The cake will be 20 different layers, each with a different taste. Yutong and his father will be able to eat to their hearts content. The doctor says that he won the lottery and that he'll use the money to buy Yutong a birthday cake. He also says that Yutong should keep the money for himself since he's sick like him. He tells his brother that he heard from his father that he was also a deliveryman, so there's nothing wrong with that. He says that his brother should keep his money for his own illness. He then says that the lottery is a coincidence, and that it's one hundred thousand, not ten thousand. He explains that he wanted to use this as an excuse for not being able to go to the birthday party, but in the end he realized that it was actually ten thousand, which is enough for a birthday party. He and his brother plan to call all of the patients of hematology and oncology and have a party for them. They also say that they can fulfill their last wishes, and now that they have money, they can do whatever they want
