Seven years ago, Wen Ruan mistakenly believed she was nothing more than Gu Nianshen's plaything. After discovering she was pregnant, she left on her own and raised their son, Yuanbao, by herself. Seven years later, Yuanbao is diagnosed with congenital kidney disease and needs 500,000 yuan for surgery. To win the prize money, Wen Ruan enters the Gu Group's jewelry design competition, where she reunites with Gu Nianshen, who has become a CEO. Having searched for her for seven years, Gu Nianshen deliberately organized the competition to lure her out and keep her by his side. Meanwhile, Su Yao and a fake mother-in-law repeatedly make things difficult for her. When Gu Nianshen's mother discovers the family birthmark on Yuanbao, the truth about his parentage is finally revealed. The misunderstanding from seven years ago is cleared up, and Wen Ruan also discovers that she is the long-lost daughter of the Su family. In the end, Su Yao is brought to justice, and Wen Ruan and Gu Nianshen finally put their differences behind them.
