Lacking funds for his brother-in-law’s dowry, Cole Stone is abandoned by his cheating girlfriend.

He makes a phone call…

“Ma’am, I give up. I don’t want to work hard anymore.”

“Sure.”

$10,000,000 is credited into his account.

Betrayed, mocked, and humiliated for being poor…

Cole Stone is forced into an engagement with a billionaire CEO whose motives are unknown.

“Ma’am, I would like to issue you a refund—”

“Do you think that my dowry can be refunded so easily?”

Cole Stone is stunned speechless.

Unfair! Absolutely unfair!

How will Cole Stone fare with this mysterious and sassy fiancee of his who never takes NO for an answer?

How will he fare in the world of elites?

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?
