The Youngest Daughter of the Villainous Duke

I possessed a character in a novel that I stopped writing as a hobby when I was in high school. My mother died in an accident, and my father is rumored to be dead right after he went to jail. Thanks to that, I became an orphan girl at the age of seven without a name. While living in another person’s house, I was exhausted from working and was caught running away. Then sold to s*ave traders. I was wondering if this life is meant to be ruined. The reputable Duke, the Empire’s greatest villain bought me. “She’s 7 years old, but was small and too thin.” Henriette, the worst villain in the original, whose hobby is making everyone act like a puppet, playing tricks on the imperial family, and threatening the neck of the aristocracy, it turned out that scary man is my real father who went to jail! But you seem a little different from the original villain. “Well, duke…” “No.” “…..Oh, father?” “That, too.” “……uh, Daddy?” “Yes, my daughter. What do you want to have today?” Henriette, who I thought was scary, is more friendly than I thought. “If anyone bothers you from now on, you have to tell your big brother, okay? I’ll drown them at the bottom of the lake.” “Shall I go see flowers with my little sister today? There are so many ornamental mermaids in the glass greenhouse. I thought you would like it, so I caught it myself. Did I do a good job?” “This slow girl! Dad called you…. No, I’m not mad! Damn it, don’t be s*upid! Ahhh! Yeah! I’m wrong! Okay?” The new brothers were definitely villains in the original, but they are much nicer than I thought. “You can do whatever you want. Anyone in the family, if you say so, will listen carefully and do what you say.” But it’s weird. The novel I wrote wasn’t originally like this. *** “….If you promise me a few things, I’ll stay with you again. I won’t leave you.” “You can see me anytime without an appointment.” “Should I? I can always run away to a place where you will never find me again.” He frowned his eyebrows. If I had known that a small word of expression would have caused such a terrible reaction, I would have kept my mouth shut then. It was when I was in the middle of regretting, “You’re mistaken. Do you think I will let you go in the first place, shouldn’t that be possible first?” “….What?” “Who said I’d let you run away?” ……No matter how much I think about it, I think I got it wrong. “If you’ll really run away, you shouldn’t be caught by me again.”
