Ji Mo has no family or relatives. The only person she has is the younger sister she grew up with in the orphanage.
Her sister's congenital heart condition has returned, and she urgently needs half a million yuan for life-saving surgery. Their birth mother, who married into a wealthy family long ago, refuses to help.
Ji Mo is furious, but her sister just lies back and waits to die, saying she understands why their birth mother wants to marry into a rich family.
Ji Mo hears that her sister's birth mother isn't having an easy time among the wealthy. Her stepson, Shen Zhiyi, is spoiled beyond measure, wild and proud by nature, and never keeps a girlfriend for more than a month.
To secure her place in the wealthy household, the woman follows Shen Zhiyi around, cleaning up one mess after another: handing out checks and talking his girlfriends into breaking up with him.
As a result, she has become the laughingstock of the rich wives' social circle, known as the "Breakup Master."
The "Breakup Master" never fulfilled her duties as a mother, leaving Ji Mo's sister with nothing but an inherited heart condition. Ji Mo decides to deliver justice on behalf of heaven.

Hoping to get a check from him, Ji Mo puts her all into getting close to Shen Zhiyi and flirting with him.
The road ahead is tough, but fortunately, he's just as promiscuous as the rumors say, so her seduction plan goes surprisingly smoothly.
But something's not right:
One month, two months, three months... He still hasn't gotten tired of her? The "Breakup Master" still hasn't shown up.
Ji Mo starts getting restless, so she tries every trick she can think of to stir up trouble.
Her hard work finally pays off, and the "Breakup Master" comes to see her at last.
Later, when the truth reaches Shen Zhiyi, he goes mad and finds her, backing her step by step into a corner, his expression icy.
His long fingers brush her chin as he says in a low, hoarse voice, "Ji Mo, you played me? How dare you?"
