Su Zhenran is a hardworking, ambitious girl who has never known the warmth of a family. Quiet and withdrawn, she avoids interacting with others, until He Yi comes along. This sunny, humorous boy falls for her in high school: an ordinary-looking girl who always wears her uniform, yet somehow stands apart. She thinks that after finally opening her heart, she’ll find a warm and loving romance. Instead, she meets a tragic end: her lover leaves, her mother dies, and her cousin Qin Yiruo leaves her child in Su Zhenran’s care, making her swear to her mother that she will never reveal the child’s origins. Still a university student, she is disgraced by slander and eventually expelled.
