The real daughter Jiang Wuxi was exchanged by Qu Xinlian when she was young and grew up in hardship. After her mother passed away, she faked her identity and sneaked into the Lin family as a nanny, taking advantage of the Lin family's weaknesses to collect dirty information. In the process, she had emotional entanglements with Fu Shiyan, Chu Fang, and Lin Yaoshen, and used the opportunity to disintegrate the Lin family. During the investigation, she discovered that Lin Xiaoyuan had known the truth about the exchange but connived at everything. She also found out that Lin Anni and Lin Yaoshen were not her biological children. In the end, Jiang Wuxi exposed the evidence of the Lin family's crimes, leading to their downfall, regaining their identity and wealth, letting go of their hatred after making emotional choices, and starting a new life.
