I appreciate some readers' apprehension, but there's beauty in fiction giving the sorts of happy reality couldn't or "shouldn't", provided it's not at actual people's expense (like giving kids hope their divorced parents will reconcile).

Maybe the "correct" ending is the pair treasuring their newfound freedom as adults to compensate for the lack of childhoods, just like the "correct" villainess endings probably entail prison sentences instead of an enemies-to-wives-to-parents rondo. But where's the fun in that?
