Bound sovereign: Reincarnated with the lust system

Eran, a betrayed man from Earth, dies in the most humiliating way possible—poisoned by the woman he loved and framed by the brother he trusted. When he wakes up, he finds himself reincarnated into a medieval-fantasy kingdom where nobility rules over peasants with arrogance. But unlike others, he is granted a forbidden [Lust Domination System], a cheat-like power that feeds on desire, intimacy, and submission. His growth isn’t through slaying monsters, but through conquering the hearts and bodies of women, bending even the most prideful to his will... He gains power against his Rivals, but manipulates them through his Harems by turning even the Greatest enemy into parts of his extended Harem. Eran’s chest burned as the poison crawled through his veins, his sight dimming. He looked up at the woman he once called beloved. She stood there with a cold smile, her fingers intertwined with another man’s hand—his own half-brother. “You were always too soft, Eran,” she whispered. “Too trusting. Too easy.” The last sound he heard was their laughter, mocking him as his body collapsed onto the cold marble floor. Darkness swallowed him.
