“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…

“Sanye, do you know that you are like a book. Every time I see you I want to … sleep.”

After some hesitation, Xin Ai finally decided to approach Jian Sanye, who was famous for his power. She tried hard to make him happy, justify thousands of ways, sacrifice self-esteem and dignity, with the main goal to find her missing sister.

Three months later, the man threw a check in front of her, “I’m tired.”

Xin Ai stood up with her innocent body without a single strand, smiled wryly and said, “Alright, I’ll go as far away from you as possible.”

When they met again, Xin Ai closed her eyes to Jian Sanye’s presence, it made the man angrily push her against the wall, “We’ve slept together a few times. Is it so easy to forget me?”

Xin Ai smiled so sweetly and teasingly, putting her hand on the shoulder of the man, “Sorry, I have slept with quite a few men, sometimes I can’t remember it even happening. If I may know, what’s your name, sir?”

“Just watch, I’ll make you remember who I am.”
