This chapter opens with a knock at the door of the preceptor's house. It's the daughter of the grand preceptor, and she's there to greet her childhood sweetheart, the prince. The prince and the girl have been childhood sweethearts ever since they were little kids. The girl's name is Biyuan, and the two of them have been together since childhood. Biyuan tells the prince that he's already a grown-up man, and that he can't take care of himself. She also tells him that she came to learn how to cook. The kitchen is dirty and greasy, so it's not a good place for a young lady. She tells him to make a dish of mushroom and seasonal vegetables. The dish is called Jubilee of Three Treasures, and it has a lot of umami in it. The lady tells him about the dish's ingredients, and then she tells him how he should have taken care of the dish. She says that he was the one who made the dish and then pushed it to her after he failed to finish it. She scolds him for pushing the dish to her, and says that she'll have him send her back to her master's home. She's annoyed that he hasn't opened the door yet.
