Three years have passed since the last time we saw Cai sinian, and she's been nominated for the "best actress" at the "pearl international film festival" . She's got a new ad, and it's all about her sister, Luo feng, who's just returned from a trip to Hong Kong. Cai tells her sister that he's not coming back to her house, and that she'll have to rent out her room to Luo. She also tells her that she has a new roommate, and they're going to be roommates for a while. Cai's dad and brother-in-law come back from Hong Kong, and Cai tells them that they've just rented out Luo's room. They're all excited to see each other again. Cai says that she and her sister are both teachers from the same university, which means that they have the same student, and the two of them are the key recruits of the university. They all think that Luo is dead, but a rumor has it that he has applied to retake the exam at the university, and is now likely to arrive in the city. Everyone thought that he was dead when he disappeared, but he actually went back to school just like any normal person. Everyone is looking for him, regardless of who he is or what he stands for.
