Zhang Zhen first meets Chen Chen, a freshman, and Wu Di, the rich playboy with him, immediately begins pursuing her. Wu Di never expects Chen Chen to be unmoved by his advances, so he steps up his efforts, only to end up beaten black and blue and utterly humiliated.
By chance, Zhang Zhen and his close friend Shi Cong are sketching beside the campus lake when Chen Chen quietly watches Zhang Zhen's focused expression for a while. When Zhang Zhen turns around, she hurries away, leaving him only the sight of her back.
After running into each other by chance several times, Zhang Zhen and Chen Chen start dating. On their second date, they visit a nursing home to see Chen Chen's grandmother, who has Alzheimer's disease. With Zhang Zhen's company and comfort, Chen Chen finds more courage to face the future and tells him how grateful she is.
After returning to the dorm from the nursing home, Zhang Zhen gets into a fight with Wu Di and Cai Tong. Outnumbered, Zhang Zhen takes a brutal beating. But the incident brings him and Chen Chen even closer, and they officially become a couple, relying on each other.
