Seven years ago, Jiang Yue, an orphan from an ordinary family, painfully left Gu Huaichen so that he could return home for treatment of his heart condition. However, she was involved in a car accident, which left her mentally impaired, and gave birth to their daughter, Nian Nian. Gu Huaichen was told by his father that Jiang Yue had died. Unable to forget her after all these years, he repeatedly refused arranged marriages. Seven years later, while begging on the streets to raise money for Jiang Yue's surgery, Nian Nian finds Gu Huaichen's jade pendant, leading him to discover that Jiang Yue is still alive. Meng Yurou, the woman chosen for his arranged marriage, repeatedly harms the mother and daughter, but unexpectedly helps Jiang Yue recover her memories. Jiang Yue also uncovers her true identity and reunites with her biological mother, discovering that she is actually Su Yuening, the long-lost daughter of the Su family. In the end, Meng Yurou's crimes, including orchestrating a car accident, are exposed, and she is sent to prison. With their families' blessings, Jiang Yue and Gu Huaichen finally hold their wedding, and the family of three begins a happy new life.
