Lu family's daughter Lu Zhaoning was kidnapped when she was little to save Fu Siyu, losing her memory and becoming Ye family's adopted daughter Ye Ningning. Fifteen years later, she works as a cleaner at Fu Corporation. Her adoptive sister Ye Xueer steals her hair for a paternity test, impersonating the Lu family daughter, stealing her fiancé, and beating her adoptive father in an attempt to silence him. The whole company laughs at her, but she doesn't explain, only tightening her grip on her broom. Only Fu Siyu stares at the protective amulet on her neck—the one he personally put on her when he was little. Yet the test results point precisely to Ye Xueer. Her adoptive father remains unconscious, and the truth is buried. The amulet is still there, and Fu Siyu is still there, too. Can Ye Ningning hold on until her adoptive father wakes up to expose the truth?
