I've never seen the appeal of forced engagements.
Personally, I think reversing this would be of greater interest. After all, though I have not read ahead, or have any clue how it will end in terms of having examined the documentation, it's painfully, painfully obvious they're eventually *sigh* going to get along. For everyone who will read this,the "fun" will be watching the tedious process happen.
But what if it were reversed? What if they managed to convince the overbearing and backwoods parents that this is an awful idea? Bit by bit the parents realize they've made a dreadful mistake. Both tyrannized "engaged" couple members are finally given their leave of each other.
Now THERE's a story!
