Ceo's Mandatory Contract

In a transaction, she sold herself in exchange for a chance of survival for her father. With a contract, he bought her out for three years, just to fill the bone-eroding hole in his heart. Su Wan's world completely collapsed on the day when the notice was given that his father was critically ill. The sky-high cost of surgery was like the mouth of an abyss, swallowing up all her hopes. When she was at her most desperate, that man appeared like the emperor of the night and threw down a cold contract. Nangong Yao, a powerful business tycoon, is cold, paranoid and in control of everything. He gave her luxury and the rebirth of a close relative, at the price of everything she had. He gave her the ultimate pampering, but also gave her suffocating pain. The ubiquitous control, the pressing plunder, and the deep gaze that seemed to be looking at another person through her... All made her suffer day and night in this golden cage, unable to breathe. You are just a shadow I bought, never try to get my heart. Your body, your soul, your joys and sorrows belong only to me from now on. When the tender old love reappears, when the dust-laden family secrets are brutally revealed, when the truth about the substitute emerges... This sadomasochism that started with a transaction has been entangled to the bone and will never end. He pushed her into hell with his own hands, but when she was about to be destroyed, he burned the world for her. She hated him to the core, but she also lost her heart in the endless sinking and struggle. This is a game in which whoever is moved first loses, and it is also a shackles of purgatory forged with love and hate. It corrodes the heart and bones, and you will not rest until you die. Will they be able to settle all their debts, or will they be entangled for a lifetime?
