*Who would have thought a precious legitimate princess was forced to secretly marry a predator in the middle of the night when the silver moon shone bright in the middle of the starry sky?__“Your wench mother seduced my father and made you!”Consumed by rage after her half-sister insulted her mother, Reneira Dorient unleashed her secret power. Magic was taboo in the seven kingdoms, and those born with it must be burned. But she was a precious princess to the Kingdom.The royal family kept this secret with them and locked away her power, however, the King had a far darker plan: he forced her into a marriage with the evil prince of Thegara, a ruthless barbarian who had bathed in the blood of countless victims, as rumors said. Their union was the King’s strategy, she was a tool to win yet another war.The night the prince arrived to claim her, Reneira braced herself for the inevitable circumstances. However, nothing could have prepared her for the truth that this wasn’t just a marriage.Her new husband was a sweet torment, an immortal, god-like bully disguised in an impossibly beautiful human form with no rival. His every gaze felt like a punishment, and his sinful aura tempted her in ways she never expected. This god of lust refused to touch her or accept her as his true wife.Believing that her dignity was lost forever, she resigned herself to her fate, hoping to make a home in the hell she’d been thrown into. But fate, as it often did play, had other plans. She came to encounter a gorgeous yet wicked ex-mistress who didn't want her as his wife too and constantly attempted to push her out of the way...__“Don’t even think about seducing me by licking your lips like that, doe-eyes!” He breathed in her ear as he joined her in bed, shirtless, his muscular abdomen rippling with each movement.“I… I’m not doing it on purpose!” she stammered, her breath catching in her chest when he wrapped his arm around her waist and pulled her body against him.His mouth hovered near her ear. “I’m going to make you forget what happened today. My body is yours as compensation.”Butterflies fluttered in her stomach. Rolling her eyes away, she tried not to meet his dangerously alluring gaze. “You said we’re not a real couple, and I’m not your true mate. What’s changed your mind?”He grinned widely, grabbing her chin and leaning in so close that she could feel his warm breath against her skin. He used his tempting aura to compel her to meet his gaze. Her treacherous heart didn’t defy him again, he could hear it racing.“That term of the treaty no longer applies. From now on, you’re truly my wife, Doe-eyes. Only mine.” He paused, studying her body’s response.“Shall I stop here?” he whispered, his breath sending a shiver down her spine.Once again, she surprised him. The answer was the opposite of what the arousal scent of her body suggested.“Yes. You should stop.”“So you’re going to play a naughty game, wife?”...
