I try to read all 7 chapters to have better judgement, but no change, that man have his "fun" growing up, and called her as "MY precious girl" while going out parties all his might, he is immature, doesn't have responsibilities with his works, and put them all on her. The only strong point of him which the MC always point out is his pretty face, nothing else.
The late marquis, the house workers,.. all shipping them together, but why? Doesn't she deserve better life? Why forcing her into marriage relationship again her will again? Of course they will always favor their master more, but she shouldn't be treated like an aiding tool to that childish, wretched mind.
And why called her as "villainous" when she does nothing villainy?
That first love should have ended right there, why trying to dig it up again? At this point i'm worry that the author will make her bearing a child as a way to mend their relationship or trying to white- washing him again as a good character.

Once an abuser, always an abuser, he might be soften if he really got her, but if conflicts happen again in the future, he might use your past again as ways to hurt you.
I am unable to enjoy the type of story which woman have to accept or forgive trashy man
