NTR fanatics are the loud vocal minority, the thing they have advantage with is the Beta Cucks are fine with throwing a ton of money at any Devs that develop for their taste. But overall NTR is a niche genre enjoyed by a minority of people on this site. Contrary to the beliefs of many of said fanatics, which seem to have that delusion of being a majority, where did society at large ever give any of you the notion that getting cheating on and losing your partner was a highly sought after experience? Its not, its a couple % of people that might enjoy that sort of thing. This site isn't a website that was created to cater exclusively to a kink, but to pirate adult games in general, and that mean the ratio of people here reflect actual society, so a small minority of NTR enjoyers, and again the only reason for the large flow of NTR games is the large flow of money that goes to devs to pay for them, not actual popularity.
Also like I said my point is perfectly justified, it wouldn't make sense for any of the final endings to be NTR since it would be counterproductive to the entire narrative. As I said for some 'what if' bad endings along the way NTR would work, but it wouldn't fit any of the real endings to the game. The fact you are too obsessed by your kink to be able to acknowledge any narrative that doesn't go along with it is your problem. Also this game isn't purely NTR, the fact their is a NTS path to begin with shows this, the fact that the narrative is tailored if anything like I mentioned many times with the whole Elven Cook and his slut wife point toward NTS supports it too. NTR is what is going to inevitably happen in the dungeon, but once back out it wouldn't make sense to keep happening from a narrative perspective.
Or did you fail to notice the whole thing is purely supported by some magical effect within the dungeon, and once they'll be back out of said dungeon it will stop affecting Mia and the MC is going to be able to fuck her again, so the notion she'll leave him afterward for anything else than a early 'bad ending' doesn't make any narrative sense, if the Dev actually intend for the story to keep up with its own current existent narrative, as I stated she is a pariah amongst people, and the MC love & care for her, how would she find anyone else able to actually compete once back out of the dungeon's influence? Its impossible.
At worst she might be fucking around while the MC will effectively be a Beta Cuck that let it happen, but guess what, that is NTS not NTR, and like I previously said its also an outcome already advertised if anything by the narrative, so yea their is no scenario where it could end with NTR, which mean the MC losing Mia, that wouldn't completely sacrifice the narratives and characters just to cater to your kink.
Like I said at most Mia might trade the info on witches for sex with the Merc Leader, but its not like he could hold that information over her indefinitely, it would be for a limited period of time after which she would be unwilling to have him keep delaying her, after that is done she wouldn't have any reasons to not return to the MC, so its not like he'd actually lose her to him, she has shown zero incline toward any other characters outside of the MC outside of the dungeon, so the notion once back out she'll will find anyone suddenly of interest to her would be ridiculous, why would she want to leave the MC for any people that were disdainful or hateful toward her? It would be completely stupid.
And before you start screaming about corruption, again go back to my earlier point that this is all magically induced, once that effect is gone their is no reason for her to really be remain fully corrupted like that, which is the major difference with most NTR stories with an NTR ending where the girl get actually corrupted, not just drugged up temporarily and expected to abandon her boyfriend over it.
