A Bewitching Maid, Bound to the Mad Emperor Night After Night

[Both leads are reborn + System + devoted one-on-one romance + sweet and angsty] Shen Qingwan transmigrates into the role of a servant girl who serves as a stand-in in the tyrant's bed. The System warns her: [Xiao Jin's corruption level is at 99%. Stop him from destroying the world!] She gazes at him seductively and clings to his neck. “Your Majesty, I know how to please you better than the Noble Consort.” Later, as blood washes across the land in the Golden Throne Hall, he grips her waist and sneers. “Wanwan, where is your heart?” She plunges a dagger into his chest. “Your Majesty taught me well. Only the heartless can survive.” After living again, he imprisons her atop the Star-Picking Tower. “If you run again, Wanwan, I'll shatter this kingdom and play with you among the ruins.” She smiles as she strokes the teardrop mole beneath the emperor's eye. “How fortunate. This time, I'm here to cure your madness.” He chases as she flees, with nowhere to escape. Across two lifetimes, two madmen bend themselves to her will.
