The legitimate daughter of the Marquis's manor, Shen Zhiyi, is reborn back to before her coming-of-age ceremony, only to discover that her entire family consists of villains: her father is corrupt, her stepmother poisons her, her half-sister takes her life, and her fiancé uses her to climb up. In this lifetime, she will no longer be a naive little white rabbit; she will be a black moonlight, smilingly handing over poison and kneeling to hand over knives, tearing everyone's scripts to shreds. The female protagonist is not reborn to become kind; she is reborn to become even more wicked, using the villains' knives to kill in the villains' game.
