It's not clear whether "rainbow paradise" is involved in the testpaper incident, but it's clear that Li Wenwu is bullied by the group. The group has forced students with well-off families to join, but they haven't gotten anything back from them. The one who bullies the most is the key member of the group, and he's going to show his true face. He tells his sister to open the closet and there's a birthday present waiting for her: "swish clatter clatter" . He says he'll make his wish come true, and that's because the pact with the principal has been broken. He then tells his brother-in-law, Zhengzhou, to come home with him. He explains that his family's ancestors listened to divine instructions and set up an underground lending company. The family became rich, but the same time, they also had to take the punishment of having a dark personality appear in the family. This dark personality will threaten the company, and the family has to destroy the person who threatens the company. Zhengzhou says that if he sees his sister, he should bring her to his mother's room. He'll be the new leader of the underground lending organization, and she'll have to live with him in her room.
