The Su family has twin daughters. The elder sister Su Qingyao is bright and public, and is the person Gu Shiyan cares about. The younger sister Su Qingyan is taciturn. She was fostered in the countryside since she was a child, like a shadow that cannot be seen.
On the eve of the wedding, Su Qingyao eloped for love, leaving a mess behind. In order to protect the Su family, Su Qingyan was forced to put on a wedding dress and become Gu Shiyan's substitute bride.
Gu Shiyan, the business emperor of Haicheng, was cold and paranoid, and only had Su Qingyao in his heart. He hated this substitute who tried to replace his sweetheart with a similar face, and was extremely mean to her: "Remember your identity, you can never replace her."
