The dean of the medical school, Professor zuo, arrives at the bar. He tells the professor that he has a favor for him: he wants to borrow Xiao for an hour so that he can wait outside for him to return. The professor tells him that he must be mistaken, for he has just seen Xiao in a new coat. When the professor asks where the girl from the pharmacy class is, the professor replies that she is the one who follows Xiao because she is bored. He says that he will clean up the floor after the class so that no one will come to the school from now on. When he asks if there is a place where outsiders cannot enter without an identification card, she replies that there is. He then asks if he can send a recording of the incident to ime.
