Synopsis：Office worker Lin Shuang wakes up to find herself trapped inside the otome game “Demon Butler,” reborn as Lilith Klein—the infamous villainous duchess fated to be slaughtered by four demon butlers. In the original plot, Lilith’s cruelty drove the World Serpent Yegad, the Lop-Eared Rabbit Lyle, the Hellhound Kerberos, and the Bat-Succubus Mord to sky-high Dark Values, until they joined forces to execute her. Now bound to a Fate-Changing System, every move Lin Shuang makes is a dance on the edge of death: she rescues the abused, mute Lyle and uses her own blood to heal him in exchange for a fragile sliver of trust; she descends into the dungeon to strike a perilous deal with the yandere male lead Yegad, barely twisting her doomed ending. Armed with the sharp mind of a modern corporate veteran, she tears apart the fake-innocent heroine and her biased mother, dismantling them with precise psychological tactics. One by one, the four demons who once lived for vengeance are tamed, turning into dangerously possessive yet utterly loyal butlers. In a gothic world where humans and demons coexist, she seizes power, rewrites the script, and forges her own legendary rise.
