It's sad how this is an interesting idea that could have more historical messages about slavery and the culture of (what is probably native Americans despite w/e they call them here) but that instead the author just uses it as a shallow tropey theme and does nothing of substance with it.
Like...same old rapey ML and soft submissive MC, even though in this world the MC should be the assertive one.
At first I got vibes from the MC that he was cold and apathetic after his family's death, but he's actually just a doormat. And ofc the story had to use the dumbest reason of 'jealousy' for the MC to be raped. There is GOOD reason for ML to hate all white-skinned, or those who brought his family to ruin, so even if he raped MC because of that kind of race hatred, it would actually be less cheesy than the 'ugh I'm angry and jealous'.
