Rather Than the Son, I'll Take the Father

I possessed a supporting character who died of heartache because of her shitty husband. If I can’t avoid the marriage, why don’t I just change my husband?
“Okay, I’ll get married.”
“Wise choice. Then let’s have a wedding ceremony that isn’t too ceremonious. Following that, I’ll need you to go down to the Fief and behave like the lady of the house until I call for you. Naturally, there won’t be any time to spend in leisure whilst dousing yourself in luxuries.”
“Not to you, but to your father.”
“…… Pardon?”
“He’s single. Is there a problem?”
