It's 2 in the morning, and the girl is excited because she's going to meet up with her sister at the fan meeting. She's also excited because her bag was stolen and all of her homework exercises have disappeared. She wants to borrow money to buy more books, but she can't because her family is going to scold her for not being a member of the study club. The girl says that she still has 300 yuan in her bank account, and that's enough to buy some books. But the girl's not buying it. She says that her sister has been gone for two days, and she'll have to go back to school to study hard. She doesn't want to be caught lying, so she promises to do her homework hard.
