From the day she reluctantly married as a substitute, she lost—lost to love.

Jiang Kexing, president of Haode Group, is unable to let go of the death of her lover, Lin Chuan, three years ago, who died saving her. Upon discovering Pei Xubai, who bears a striking resemblance to Lin Chuan, she forcibly interrupts his wedding and uses her power to coerce him into marrying her. Pei Xubai, harboring resentment, joins forces with Ren Wanqing to seek revenge, constantly humiliating and harming Jiang Kexing. Despite her pain, Jiang Kexing endures it repeatedly because of Pei Xubai's resemblance. The core conflict revolves around the emotions of a substitute, the oppression of power, and revenge.
