Shen Qingxian, the daughter of the guilty minister, was forced to marry the powerful, ruthless and bloodthirsty Dingbei Marquis Xiao Jue in place of her beloved sister. On their wedding night, she discovered that she was not only a chess piece that could be discarded at any time, but also the perfect substitute for "White Moonlight" in Xiao Jue's heart. In the deep compound, she endured all kinds of torture from Xiao Jue and the conspiracy of everyone in the house, and used her amazing resilience and resourcefulness to survive step by step in a desperate situation. The highlight is that when Xiao Jue couldn't help but fall in love with the soul of this substitute while being used and tortured day after day, he personally pushed her into the abyss of eternal destruction. When all the truth was revealed, the so-called "White Moonlight" turned out to be a shocking scam, and her identity, Shen Qingxian, was the most critical part of his revenge plan from the beginning. The plot revolves around "extreme sadomasochism" and "chasing his wife in the crematorium". The female protagonist is reborn from a humble stand-in to an independent woman who can stand side by side or even confront the male protagonist. The two pull each other in the whirlpool of love and hate, and finally reveal the blood feud between the two generations.
