@Utter-disgrace To be fair, she did just insist on moving to a cold and barren place to marry a banished traitorous duke with a violent reputation because she thinks he's attractive and lonely. She looks quite young and has lived a lavish life too, if this wasn't a romance manhwa she should...
In an ideal story this would be the point where she gets a divorce and starts a new life, starts a business with the alimony and those negotiating skills and maybe falls for a guy who'll actually appreciate and love her.
