If the MC reject defintively a LI , said LI can't be considered a LI anymore in the story and become a normal character.
Normal characters getting in relationship (or just fucking) with other normal characters should always be considered normal, because it is normal people behaviour, exactly the same as normal characters not getting into a relationship (or not fucking) with other normal characters.
nothing to do with some shitty kink/fetishist crap.
Now what i don't like for that scene between Eva and Chloe or Leon is that it is indeed voyeurism and is forced on the reader, viewing it should be optional so people not into voyeurism wouldn't be forced into it.
This I agree. But, then it not just rejecting her. Moreso, it is more of a Hard Hard Hard reject for you to obtain that scene if I remember correctly. You have to keep rejecting her or sidelining her content.
Okay. Watched the scene and Leon said this
Leon: Such a shame you had to be turned down twice to realize that.
Eva: What do you mean?
Leon: Look, I'm not stupid, and I don't being third pick - still had sex. But we both know that if we had everything our way tonight we'd be all over somebody else.
And yeah... The sex scene is really dry devoid of anything really.
I can't see a pairing or anything beyond this with those two if we respect the writing. Chloe and Eva on the other hand, eh maybe it could be. But man... this game is harem and you really need to lay it thick on rejecting them for this to happen.
So, you do you.
