On the night when the Lin Group went bankrupt, Lin Shuyue fell from the clouds into the quagmire. Her father jumped off the building, her mother was seriously ill, and her fiancé betrayed her. In order to raise money for the operation, she was forced to sign a "contract of sale" and became the "contract lover" of the most mysterious man in North City - Lu Chenzhou, the leader of the Lu family chaebol.
Lu Chenzhou, recognized as the "Living King of Hell" in the business world, built a billion-dollar empire with iron-blooded tactics. It is said that he is ruthless and not close to women. He chose Lin Shuyue just because she was the daughter of his enemy and the most perfect pawn in this revenge chess game. He wanted her to be ruined, and wanted her to taste what it was like to go from heaven to hell.
However, when this seemingly weak woman protected his mother's relics in the heavy rain, when she shouldered the huge debt on her thin shoulders but never bowed her head, when she was bruised and bruised time and time again in the traps he designed but still stood up stubbornly - Lu Chenzhou's heart that had been frozen for ten years began to crack for the first time.
He thought he was hunting, but he didn't know that he had already become prey; she thought she was seeking survival, but she stepped into the gentle cage he carefully woven. When the truth was revealed, and the blood feud and deep love were intertwined, they discovered that they were both orphans who were caught in the massacre ten years ago.
Should they continue to love and kill each other, or should they work together to avenge the mastermind behind the scenes? When the empire of hundreds of billions was on the verge of collapse, and when the decision of life and death was before him, Lu Chenzhou pledged his entire country to him: "Lin Shuyue, I surrender in this game of chess. Not to you, but to my heart that wants to love you to death."
