It's historical manhwa were the same makes a deal with one woman that is the villain till that point, that he will give her a child to make the child's life however she wants, but to not hurt him or the uke anymore. That was near the end I think.
In the villain background story I think she is a psycho but she is a woman and didn't have an option to live a life how she wanted, but is satisfied to make a life story for someone.
I'm mixing other stories for the rest of the part so I'm not sure.

oh my God I'm so sorry I misread "villain" as "Villainess" here how about this one?
