Luo feng is invited to his father's house for a banquet, and his sister begs him to accompany her to the party. He is not free to go, however, because he has something to do. He tells his sister that he is surrounded by many other women, and that he will never lose his love for her. He wonders if it is possible that he likes other women too, but he is confident that he can never lose her love for him. Sister jiuyun thinks that the tactics of his brother are very useful, and she is amazed at how quickly he deals with situations like this. Before he leaves, he tells his brothers that he has found her, and he will send her the address. He asks his brothers to help him prepare for his return, and they all agree to do so. When they arrive at his apartment, they are surprised to find that his sister is actually in the same apartment building as him. They are also surprised to learn that his room is under water-leakage, so he wants to stay there for a while. They ask him to take them to his residence first, and when he does not, they think he has forgotten the key to his room.
