A calculating merchant of noble birth lives a comfortable life managing his guild's business at the Imperial Academy—until lightning strikes him, leaving him with prophetic visions of a disastrous future. In these visions, he's expelled from his family, branded a traitor who aids demons, and worst of all, becomes a penniless beggar. When the supposed “protagonist” of these prophecies enrolls at the academy, he realizes his countdown to ruin has begun. Now he must use his foresight to rewrite a story where he's cast as a third-rate villain, all while navigating ancient dungeons, demonic threats, and the troublesome “hero” who might be the key to changing his fate.#MoneyIsEverything

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?
