Genuine question, what are you talking about? Are you telling me the only stories that should ever be written as heartwarming? There are plenty of those and it should be that way.
But, every once in a blue moon somone writing an incest rape fetish bothers you? Nobody forced you to read this thinking it would be anything other that this, like it isn't misleading or anything it's very obvious what it's about from the beginning of the chapters. Do you consider the same thing about horror stories? About apocalyptic stories? About not real war stories? Cause those are all messed up, extremely violent themes as well.

Ah yes incest rape i love it!!!! Why make it just enemies to lovers with a heartwarming romance when you can add incest and rape????
