In the orphanage, the female lead Yi Yi and the male lead Shi Tou were childhood sweethearts, relying on each other for survival. Years later, the two were adopted one after another. Shi Tou became the CEO of the Gu family, Gu Beichen, while Yi Yi was adopted by an ordinary family and changed her name to Jiang Xinya, becoming a laborer. At the same time, Yi Yi's biological mother (the new generation head of the Qin family of the first generation) has learned of Yi Yi's whereabouts and wants to retrieve her. As the adoptive father of Yi Yi, Jiang Fu coveted wealth and prosperity, so he let his biological daughter Jiang Xinrong replace Jiang Xinya as the "Qin family heiress". And reached a marriage agreement with Gu Beichen, who was unaware of it. Jiang Xinya, who learned about the situation, wanted to tell the truth, but every time she was stopped and destroyed by her stepsister's man Jiang Hao. It was not until the adopted son of the Qin family verified the true identity of the heir "Qin Yiyi" and confirmed that Jiang Xinya was the true heir of the Qin family that Gu Beichen suddenly realized that the person he had been searching for was Jiang Xinya, not Jiang Xinrong
