To save her critically ill family, human girl Su Nian, desperate and out of options, sells herself to a mysterious organization. Little does she know, the other end of the contract is the cold-blooded tyrant who controls the city’s entire economic lifeline—Li Yeting. He is violent, arrogant, and possesses deep green pupils that can see through anyone’s heart. Su Nian thinks she has merely signed a servitude agreement, but she has unknowingly stepped into the world of werewolves—and become the “contract bride” of the wolf clan’s ruler. Li Yeting scoffs at fragile humans and believes Su Nian to be nothing but a schemer. He humiliates and neglects her at every turn. Yet her stubbornness and pure aura slip through his defenses like a poison he cannot control. On full moon nights, his untamed instincts go berserk time and again because of her. Even more shockingly, Su Nian can soothe the violent curse passed down through his bloodline. Just as Su Nian finds herself drawn to this dangerous man, buried conspiracies and the chasm between their species rise to the surface. Her unique constitution is not only his antidote—it holds the key to the survival of the entire wolf clan. When a calamity threatens to annihilate his people, he is willing to transform into a feral wolf, fight ferociously, and betray the whole world for her. This is a story of a domineering wolf ruler and a resilient human girl—a fated bond that evolves from a mere contract to eternal devotion through trial and redemption.
