Ten years ago, Sheng Yunxi was pushed off a cliff by her best friend, losing her memory and being adopted by a kind couple. A decade later, while working at a restaurant, she faces bullying from former classmates and exploitation by the owner—until she is rescued by Sheng Jingyuan. As her adoptive father falls critically ill, Sheng Jingyuan confirms her true identity through DNA testing. But her past returns with a vengeance: her ex-boyfriend cheats, her treacherous friend resumes bullying and plotting, and Yunxi soon finds her life in danger once again.
