After being imprisoned in the basement by her mother for ten years, she ended her cruel and tragic life in death when they forced her to hand over the key to the hidden treasure. Getting reborn in her teenage years, she woke up in the bed of that terrible and powerful man. This time, she must take revenge on her enemy, and now she must live.

“Whose child is it?” Winston and Yu-jin were once passionately in love, but due to a misunderstanding, they separated. Even now, Winston believes Yu-jin was involved in an affair with his father. After being cruelly abandoned, Yu-jin struggled to survive alone while raising his daughter, never expecting to cross paths with Winston again. Then one day, a fire forces Yu-jin out of his apartment, leaving him and his daughter homeless. At his lowest point, he learns that Winston’s father, Harold Campbell, left him an inheritance in his will. Desperate for any help, he decides to visit the Campbell estate. When they meet again, Winston still despises him, while Yu-jin only wishes to collect his inheritance and leave. To his surprise, Harold has left him far more than expected—but with one condition: he must marry Winston and bear another child within a year. Yu-jin tries to refuse, but reality is harsh. Fueled by resentment over Winston’s continued cruelty, he agrees to the marriage out of spite. Winston, on the other hand, makes it clear that their union is nothing more than a formality to fulfill the will. Yet, despite their intentions, an undeniable pull keeps drawing them back to each other. Both insist it’s nothing but lust, desperately ignoring the emotions that refuse to fade…

I cut from south to north,

I cut from white to black,

I will cut down the thousand mountains and the ten thousand waters,

I want the world to know who I am!

I am Gu Zhan,

Gu Zhan who wants the whole world to surrender!
