I Lost the Leash of the Yandere Male Lead

I possessed a villain, Selina, in a novel.

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 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 Selina.

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

I can't do this. I have to cure the twisted character from brainwashing!

By the way, what's this situation?

"Now that the brainwashing is gone, I'll do as I please. So Selina, please, let's do our best."

I've solved his brainwashing... but why does he seem even more crazy than before-

Did I make a mistake?
