Day and Night Imprisoned by the Yandere Regent

[1v1 + mutual purity + transmigration + obsessive love + scheming + madness] [Stunning, unstable, and possessive male lead + clear-headed female lead with an overwhelming will to survive] Ye Wuyue slipped and fell into the water, only to transmigrate unexpectedly into an imaginary ancient world, where she became a “fallen girl” in a brothel. The unscrupulous madam forced her to take an aphrodisiac, but luckily, that very day a powerful figure no one dared cross rescued her from the brothel. But being taken back to his lavish estate was just a matter of trading one tiny cage for another. The powerful man was devastatingly handsome, with an extraordinary bearing. He wielded immense power, controlled the fate of the nation, and looked down on all living things as mere insects. Yet he was a demon with a profoundly twisted mind. He took her away from the brothel only because she looked just like the one and only goddess in his heart. Born with heterochromia, he was someone no one dared look in the eye, and the world regarded him as an ill omen. On the night she arrived at the estate, he said coldly, “You’re the second person who’s dared to look me in the eye like that.” Ye Wuyue was terrified he would kill her, but he merely treated her, his counterfeit, as an outlet, tormenting her in all sorts of ways. He even used his own body as bait to constantly provoke and humiliate her. Ye Wuyue: No! I can’t give in, even if he’s gorgeous! She resolutely ran away and finally succeeded, but the wheels of fate refused to let her go, bringing them together once more. To her surprise, this time she uncovered a shocking secret: this substitute was actually the… older sister he had been desperately searching for all along? (Note: This isn’t an ordinary transmigration story!)
