[Swapped fake and real heiresses + domineering CEO + rebirth + adored by all]
Yun Yin transmigrates into a book as a supporting female character and gets bound to a System: she must conquer three men at once and raise their dislike to 100% to get home.
Fine. She's good at making people hate her.
[Target One: A cold CEO who hates people who cling to him]
She brings him breakfast. "Get lost. Leave whenever I'm around."
Perfect.
Later, she confesses passionately: "Can't you just not marry that woman..."
"All right."
Yun Yin: ? You're supposed to reject me!
[Target Two: A pure-hearted college boy with a sharp tongue and a hard heart]
She braves the blazing sun to bring him water. The boy knocks it out of her hand. "I'd drink toilet water before I'd drink yours."
Fine, that's going well.
Later, on a rainy night, the boy grabs her sleeve with red-rimmed eyes. "Yun Yin, don't leave me."
Yun Yin: ...When did I ever want you?
[Target Three: A naive, sweet rich kid]
She arranges to meet him for dinner, but the one who shows up is his devastatingly handsome older brother.
How is she supposed to raise his dislike? He's not even the right guy!
Elsewhere, the rich kid gets a System while driving. His hands tremble with excitement. The chosen one! It's finally my turn!
The System calmly says, [Your mission: conquer one person.]
The rich kid nods furiously. Sure, sure, who? A girl? Is she pretty?
The System: [Make your older brother fall in love with her.]
The rich kid: ???
The System adds, [If you succeed, your family won't go bankrupt, and you won't end up homeless.]
The rich kid loses it. "Wasn't I the one doing the conquering? How did I become a tool? Why is she the one being pursued?!"
