On the first day of college registration, Lin Hong's suitcase seemed to have knocked off Bai Xiaotang's notebook. But he didn't look back, and she squatted on the ground to pick it up silently. She only remembered the back of the leaving white shirt. Later, in the library, canteen, and playground, they met countless times and pretended as if nothing had happened. Both of them kept their love secretly hidden in their hearts for four years. It wasn't until her childhood sweetheart showed up after graduation that he panicked. His brother scolded him: "If you don't go, there will be no more people." A train ticket, a rain, and a word that had been held back for four years - "Bai Xiaotang, I have liked you since my freshman year." She cried and laughed: "What a coincidence, so do I." It turned out that the story had been written starting from that September suitcase.
