Ten years ago, twelve-year-old Xu Nianchu rescued ten-year-old Gu Jingchuan, who had been kidnapped, in a back alley in Haicheng. She helped him escape the human traffickers and called Uncle Zheng to take him home. Before they parted, Gu Jingchuan gave her a cloud-patterned jade pendant and promised, "Once I find my mom and dad, I'll come back for it." While protecting him, Xu Nianchu was cut on her right wrist by a knife, leaving an old scar. Ten years later, Gu Jingchuan has become the president of Gu Group. Using the jade pendant, he tracks down a restaurant to find his savior and repay her kindness. However, his aunt, Su Guifang, makes Xu Nianchu's cousin, Fang Mingzhu, use the pendant to falsely claim that she was the one who saved him. She also uses the debt and favor owed for the money she lent to treat Xu Nianchu's mother to force Xu Nianchu into silence and make her back down.
