we don't see this very often. a not oversimplificated starting point.
is he a good guy? at best, he is an somewhat greedy conqueror, who will bring a disaster to a shitty hole and give himself the title of savior by bringing in more progressive and inclusive rules. is he great? sure not, but somewhat capable and reasonably realistic.
is she pitiful? sure. broken woman being thrown around because of some people fighting over power. is it exclusively about sexism? nope. she is being used because she was a good puppet, young naive girl who had a history of being disagreeable. that doesn't change the fact that place is a very terribly unfair place for woman, but also makes it more realistic by giving the shitty greedy man more motives for their manipulative evillish action (even evil people should be driven towards something, that doesn't make them right, but gives the character agency and importance in the context).
when writing, it is very easy to fall into the trap of making up cupboard cutout characters. unfortunately, in story telling those are much easier to have, so we end up with an abundance of them, and sometimes the story that is being told is hit by them too much. and even more unfortunately is that despite making any story a bit more flavorful, writing anything with extra complexity is a trap in itself, since writers also have an agency of their own.
i do rejoice in seeing something like this, even if it fails short in the coming chapters. also it is always nice to see the comments on those type of story... so many within reason but also quite wrong or twisted with the commenters own bias. even if i don't get to finish the story, seeing those few comments make this all worth it.
