Lin Wan, an overworked office worker who died suddenly after staying up all night, transmigrates into the novel Dark Night Emperor and becomes a minor villain whom the hero, Gu Huai, will torment until not even scraps remain. To survive, she binds herself to a nurturing System and takes in the down-and-out young Gu Huai, who is still scavenging junk and can't even afford a meal. He's the man who, after turning evil in the future, will make all of City B tremble. She only meant to cozy up to a powerful ally, but instead she raises a yandere. By the time Gu Huai can turn the world upside down with a flick of his hand, he is looking at her with red-rimmed eyes and pleading softly, “Big sister, don't go.” Lin Wan: Is it too late to run?
