The Northern Duke Also Had No Front Teeth When He Was Six Years Old

I possessed the body of a villainess who was executed for trying to kill the female protagonist.
Since things had already turned out this way, I even regressed to properly change the original story.
“How dare you turn me into this mess?”
I never expected to regress alongside the Northern Duke, who was known as a mad killer.
To hide the fact that I had regressed, I did my best to act like a child.
I lisped my words, threw tantrums at my awkward father, and even acted cute.
But then—
“No matter what anyone says, you are my daughter.”
The father I thought had abandoned me now treated me as his real daughter.
“Didn’t we agree to hug and make up?”
“…….”
“If you still have any resentment, we can do it again.”
And the six-year-old Duke, who had once tried to kill me, somehow… seemed a little strange.
