The next morning, Yufei receives a call from an unknown caller. The caller tells him that a party will be held the next day at which Yufei's sister, Caixing, will be there. Yufei tells his brother that Caixing will be present at the party and that he will introduce Caixing to some of his new friends. He tells him to make sure that he and Caixing attend the party, because he will be doomed if Caixing does not meet his sister's expectations
