The Little Lady Behind the Villain

During my high school years, I became so engrossed in a novel that I ceased my own writing. Now, I find myself inhabiting the body of a supporting character rather than the protagonist. I am a nameless 7-year-old orphan girl... Enduring the mistreatment from others became exhausting, prompting me to escape that place. However, I was captured and sold into slavery. I believed my life had reached its end... Until I was rescued by the story's most notorious villain, Henriette. He manipulates the emperor like a marionette and is known for his extreme cruelty in the original tale, with a penchant for slitting the throats of nobility... Could he possibly be my biological father? Despite his dreadful reputation, living with him turned out to be quite tolerable.
