@Aisha1410 might be bad writing. It doesn't make sense to offer the family territory that she's trying to save as a reward. It doesn't make sense for the parents to just break the engagement because he's seeing other women knowing that breaking the engagement will put the entire family estate in a weak position which is what they want to avoid, since they've secured themselves exactly by engaging her to the mercenary. And strangest thing is the mercenary, why couldn't he wait until the engagement was officialized, we could say he was too greedy, but still, anyone with common sense would wait until the engagement is sealed, knowing they've truly inherited the family's name and power, and then start plotting their way out to be irreplaceable or whatever thy want. But no, he went full dummy mode, we can say he got too confident since he might've been the only option available to put their enemies on edge, but still, it doesn't make sense. It's either bad writing or she's lying.
