“Young master, the Zhao family’s young master faked an illness and went to future young miss’s place for treatment. . .” said a servant.

“Break his legs! Fail his organs! A fake illness? I’ll make him sick completely!” A man said.

“Yes! But young master. . . what are you doing?” The servant said, confused.

The man finished swallowing a bunch of expired pills and said, “I’m sick, gotta go find my wife for some treatment!”

- Description from Novelupdates

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?
