The Little Lady Behind the Villain

When I was a high school student, I was so fascinated by the novel that I stopped writing. And then now I have the body of a supporting character instead of the main character. It was a 7-year-old orphan girl with no name... Having to suffer the abuse of others, until I got really tired and ran away from that place. But I was captured and sold as a slave. I thought my life was over... But the person who saved me was the novel's most prominent villain, Henriette. He treats the emperor like a puppet. A person who has a reputation for being extremely cruel in the original and has a hobby of cutting the throat of aristocrats... Is that my biological father? But other than that terrible reputation, living with him wasn't bad either. "Okay, my baby" "You can do whatever you want. If you want something, everyone in the family will do what you want." Wait...I didn't write a novel like that in the first place?
