Why is the Moon So Bright?

First Encounter. In front of the teaching building, fourteen-year-old Xu Can sat on the steps, sobbing uncontrollably. Suddenly, a voice above her asked, "What's wrong?" Startled, she looked up, then was stunned by her beauty. Through teary eyes, she sniffled, held her breath for a few seconds, and, unwilling to tell the truth, said, "Teacher, I... I didn't do well on my exam." Tong Mingyue then sat down beside her and chatted with her. The next day, Tong Mingyue passed by the school's bulletin board. She saw Xu Can, the student she had painstakingly tried to comfort, ranked first on the grade's overall list, with almost perfect scores in every subject. "..." 2. Despite a lifetime of hard work, she couldn't overcome the burden of her background. Before being forced to jump, Xu Can's only regret was not being able to see Tong Mingyue one last time. When she opened her eyes again, her computer screen showed a blank document. She was back in her second year of university. Failing courses, no money, and two more professional exams looming... This time, Xu Can was gone.
