A daughter of the Gu family married for her sister, Shen Zhiyan, a business tycoon known throughout the city. He is cold, ruthless, and not womanizing, but he only has an almost pathological possessiveness towards this wife who he came to marry as a substitute. She was cautious and just wanted to live a stable life, but she was dragged into the vortex of love and hate by him again and again. He would forcefully protect her when she was wronged, and he would also imprison her in his arms when she tried to escape. His voice was hoarse: "Gu Nian, since you have married me for a substitute marriage, you can never leave me in this life." From the initial forbearance and resistance to the later deep-seated love, she got deeper and deeper into this misplaced marriage. It turned out that the so-called substitute marriage was just a trap he had planned for a long time, just to tie her tightly to his side, and from then on, he would be in love with her until death.
