The scene opens in a public place in Shanghai, where a young woman is being harassed by a man she recognizes as "guan zuan." The young woman asks the man to buy her a "bag of sanitary" , but the man refuses, saying that he is afraid of his period. The woman tells the young man that she has seen him wearing a mask and that he must be carrying a "girlfriend" . When the young woman sees the man's face, she thinks that the man must be wearing a "mask" because he is carrying a bag of "sanitary" on his back. The young girl then tells the man that he looks like "gzx," and the man responds by saying that she looks like him. The girl then says that she cannot catch the man in the act because she cannot see his face. She then tells him that he looked like her, and he responds that she looked like him, too. He then tells her that he has to return to the company because he has a painful period.
