I Adopted A Villainess And Got A Villain Husband

I possessed the eldest daughter of a villain family that tormented an adopted child, awakened her as a villainess, and eventually got wiped out.
The only ending for a villain extra is death.
I wanted to avoid Dead Flag by becoming a mother instead of an older sister.
“Can I really call you mom…?”
Where is there a place for this small and cute child to torment?
Okay, for the sake of my daughter and I, I’ll get out of this beggarly house!
“Please be my child’s father.”
The answer was a contract marriage.
And it was a contract marriage with the Duke of Anaxi, who was known as the best groom in the empire.
Of course, it was just a matter of mutual interests, so after they were safe, I wanted to leave without any regrets with my daughter.
But…
“You are a part of me. So don’t even think about leaving.”
This contract husband, even though he acts cold, is suspiciously affectionate.
And it seems like he has a secret that he can’t let get caught. I’ve found a proper way to live, right…?
