The Youngest Daughter of the Villainous Duke

When I was a high school student, I was so fascinated by the novel that I stopped writing. And now I’m in the body of the supporting character, not the main character. It was a nameless 7 year old orphan girl… Had to suffer the abuse of others, until I was completely tired and ran away from the place. But I was captured and sold into slavery. I thought my life was over… But the one who saved me was the most prominent villain in the novel, Henriette. He treated the emperor like a puppet. Someone who had a reputation for being extremely ruthless in the original and had the hobby of cutting the throats of royalty. …Is that my biological father? But apart from that bad reputation, living with him wasn’t bad either. “All right, my dear” “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?
