I Adopted a Villainess and Ended Up with a Black-Hearted Husband

I possessed the eldest daughter of a villainous family that dies out after abusing the adopted child until she awakens as a villainess.

The only ending for a villainous extra is death.

I planned to avoid every death flag by becoming a mother instead of a sister.

"Can I really call you my real mom...?"

How could this tiny, adorable kid possibly have any room to be abused?

Fine, for the sake of the flower road for me and my daughter, I'll get out of this rotten household first!

"Please become my child's father."

The answer was a contract marriage.

And not just any contract marriage, but with Duke Anaxi, the empire's most sought-after groom.

Of course, since it was only a matter of mutual interest, I intended to leave with my daughter without any lingering attachments once we were safe.

But then.

"You are a part of me. So don't even think about leaving."

This contract husband is strangely kind even when he acts cold.

What's more, it seems like he has a secret that can't be exposed.

I am choosing the right way to survive, right...?
