Only works if there is some form of attraction as well as the hate.
She hates all humans. They turned her people into slaves and treat them worse than animals.
Unless he can turn that around and work on building trust with the Elves at large, not just his harem, then she's more likely to cut his dick off and feed it to him.
I just found it really weird someone expected that sex to happen .... as of this point in the story, that's the least likely thing to happen
She already fucked him, her thirst for a big dick has always been there even if as she said it had been so long since she had a chance to indulge in it (of course this was from a place where her partner was a victim and captive but as i recall it was HER idea to use him for sex).
It would actually be pretty fun if she ended up at the hotel - the best way to humble the biggest bitch in the series into servitude on such a lowly stature as being beneath not just a human but a maid elf and this game still features heavy slave/servitude tones as an overarcing theme so she would have to comply without her influence and power should her kingdom fall (which could happen if for example the pixies are freed neutering her power source). She was on my take from the narrative the driving force which made the other elves CHOOSE humans over her. It wasnt forced... they fled her and took their lot with the humans and not just the common ones but the dark elves too.
No story is gonna work in this IMO where Lin frees Elves from slavery and wins them freedom politically whilst the High Queen is at large as she would spanner in the works any notion of giving Elves free rights as she is anti human, is one track minded with control, is seeking the technology to expand this control and of course is the very worst representative you could want to be shown for what happens when elves are loose of human control. She will need to humbled at some point so what better place than being a fuck toy to the MC (a resident in his dungeon with Jin her trainer in the ways of better serving and following her masters will ideally lol - his visit to her dungeon requiress an eye for an eye approach on that regards in my opinion but im sure she will grow to love being fucked by the MC routinely).
