Our protagonist, Yūki, once saw the legendary fighter known as King as an idol. But that admiration is crushed when, in the ring, he takes her first time. The man she revered is a total stranger, and Yuki is left in utter despair. Yet, in her lowest moment, King does something unexpected: he confesses his dual nature. He is not purely evil, he claims, but a man who holds good within him.
This confession is met with disbelief, until Yuki is forced to confront a undeniable truth: because of King’s support, the orphanage she cares for is thriving. This stark reality throws her into a whirlwind of conflict. Is he a villain, or a necessary evil? Swallowing her pride, she agrees to his offer of combat training, convinced his motives are merely a pretext for more lechery.
But King surprises her. The training is intense, serious, and devoid of the perversion she anticipated. As they spend more time together, Yuki begins to see glimpses of the man who keeps his promises and shows a flicker of something resembling honor. Against her will, her understanding of him becomes complicated, and a confusing new emotion begins to stir in her heart.
King’s true, desire is revealed: he wants Yuki to bear his child.
