I Picked Up the Precious Daughter of the Villain

The little orphan, whom she raised, was somehow the daughter of the villainous Duke.
He thought his daughter was dead and went crazy.
One day, when I was rolling with my feet because there was no way to deliver the news.
The Duke rushed into the house.
“If you give up the child, I will kill you painlessly.”
“Don’t kill Mom!”
She almost died after being mistaken as a kidnapper but was saved thanks to the child.
No matter if he was the father or whatnot, she cannot entrust the child to such a dangerous human being!
That’s how the shared lifestyle of raising a child with the villian began.….
This man, he is very different from what I thought.
“I’ll give you my life, so please protect my daughter until the end.”
I feel sorry for him.
“Are you testing the limits of my patience?”
He was seductive.
“For me, there was no woman before you, and there will be no woman after.”
And also straightforward.
What’s more, even the child considers me her mother…
Can I get away from this dangerously attractive villian?
