Any Historical Romance About Raising a Yandere Villain from Childhood? Master and Disciple, Senior and Junior Sister, or Siblings

I want books like The Kid I Raised Online Turned Dark and Started Plotting Against Me. It’s fine if she didn’t raise him from childhood. I want a white-and-black, yandere male lead who’s been plotting against the female lead all along, while she’s determined to guide the villain onto the right path, only to fall for him in the end. Ahhh, I need this so badly!
