Du mian and Cang shu have gone to the top of the school's roof, where they've been bullying each other. Cang-shu has jumped down, too, because he's so upset about what's happened to Du-mian. He's also bummed that he'll be missing class with Du-Minjie. He doesn't know why they're both missing class together, but he can't help feeling sorry for them. He wants to be the first one to die, and he wants to die for love. He also wants to know why both of them are absent from class together. He wonders what would happen if they really loved each other, and if they died for love, that person would have to be me . So, he asks. What's going on? Well, it turns out that both of the students are missing from class because they went to the roof, and they caught a cold from the wind on the roof. They didn't want to die because they loved one another, but because they fell in love with one another. They're so sorry that they couldn't go to class together because they were both in love, and that they fell for one another's love. So what are they going to do now? They'll have to figure out who to apologize to, and what to say when they apologize.
