In this chapter, we learn that the real challenge for the protagonist is to find a way to keep his true identity a secret. He has a headache from watching too much of the same old thing, and he's afraid that if he doesn't find a solution, he'll lose his "true identity" forever. He suggests that he watch the last season's advertisement and pretend to be the girl in it. The girl in the ad is named "Tang xin" and she's very pretty in the photo, so the protagonist wants to make sure that she'll look just like him in the real life. He's also worried that if the girl's clothes are too feminine, she won't be able to wear them in real life, so he wants to pretend that she is a boy in order to get the girls to agree to change their clothes. He wants to play the role of the boy so that the girls don't need to find someone else to act like him. He also wants to get them to agree that the girl and the boy should share an ice cream together in the park, so that they don'T have to find another girl to act as the boy in the scene. He thinks this is a good idea, since it's more authentic and meaningful than the "original" story.
