When Yun Ye opens her eyes, she and her sworn enemy, Lu Jingchu, have traveled ten years into the future.
Yun Ye glances at his pecs, then turns and walks away.
She messages her best friend: This is terrifying. I just got totally exposed in front of Lu Dog (swimsuit edition).
Best friend: Are your couple's bedroom antics something I get to hear about for free?
Yun Ye: ??? What are you talking about, couple? Sweetie, how many drinks have you had?
Her best friend immediately sends her a screenshot of Lu Jingchu's social media post: a photo of Yun Ye and Lu Jingchu's marriage certificate.
Yun Ye: ...How did I end up like this? Did the Yun family go bankrupt?
Best friend: No, you just became a fake heiress a month ago.
Yun Ye: ...
A seventeen-year-old high school student stumbles into the adult world of a twenty-seven-year-old, like a lamb among wolves. To keep up the charade, the sworn enemies agree to work together.
They'll put up with each other for a year, then divorce, split the money, and go their separate ways.
On a couples' reality show, as they watch other couples feed each other,
they look affectionate on the outside, while Yun Ye rises onto her toes and whispers devilishly in his ear: Your white moonlight and your best friend are so lovey-dovey. You never thought it'd turn out this way back in high school, did you?
Lu Jingchu: ...
At a family gathering, they all watch Yun Ye's new drama.
They look affectionate on the outside, while Lu Jingchu leans in and chuckles by her ear: You acted so well. You perfectly captured the character's bratty, childish traits, just like when you were in high school and wanted to fight me because the leaves turned yellow and you said it put you in a bad mood.
Yun Ye: ...
Yun Ye: He called me bratty and childish. Who could put up with that? Divorce!
Lu Jingchu's gaze darkens: No divorce. I put up with you secretly loving someone else for over ten years, so you can... put up with this a little longer.
*The white moonlight isn't real. They're each other's first love.
*Fake and real heiresses, but the real heiress isn't villainized.
