Xu Qing, an obstetrician-gynecologist, returns home after five years of academic training abroad. She believes her boyfriend, Song Cheng'an, will finally fulfill his promise to make their relationship public, but at her welcome-back banquet, she catches him announcing that he is expecting a child with his god-sister, Lin Xiaoxiao. Her five years of devotion become a cruel joke. Xu Qing announces that she will be getting married next month, cutting ties with her old relationship. Lu Huaichuan, the man who once saved her life and has quietly protected her ever since, arrives just in time to give her open affection and the respect she deserves. The two marry successfully, and Xu Qing publicly exposes that the child is not Song Cheng'an's, finally leaving her misguided love behind and welcoming a peaceful, happy life of her own.
