It's been a long time since we've seen the protagonist, and now he's back in his room. He's in a bad mood. He tells us that he met his crush, Xiaohua, when they were both students at the same university. They fell in love right away, but after a while, he learned that she'd had some bad things happen to her, and she was depressed for a while. He was just in his third year at the university, and he wanted to help, but he ignored his mentor's warnings, and they ended up falling in love, but she ended up jumping off the roof of the apartment building. He asks why she's crying again, and the protagonist says that it's because of his ignorance and incompetence, which indirectly caused her crush's death. He says that if he hadn't come for his internship, she wouldn't have witnessed his death, but that love will always remind him to help others.
