Rather Than The Son, I’ll Take The Father [Novel]

"Not you — I'm marrying your father."
I possessed a supporting character who died of heartbreak because of her trashy husband.
If I can't avoid the marriage, then I might as well change the groom, right?

"Alright, I'll marry."
"A wise decision. Then, we'll hold a simple ceremony. After that, I expect you to go down to the estate and behave properly as its mistress. Needless to say, you won't have the luxury to idle away your time in extravagance."
"Not you. Your father."
"......Pardon?"
"He's unmarried, isn't he? Is there a problem?"
