You didn't understand, if there was no hint of NTR from the beginning of the game or if there isn't a way to avoid it, then it completely ruins the game. If the author wants NTR in the game, they should either say it in the beginning of the game or make it avoidable, because most people don't want to waste so much time waiting for updates, following the game for month if not years just to get NTR in their face and having to drop the game.
I don't care what kind of Kinks they add as long as it's said before the user waste too much time. I don't even like futas, i actually kinda hate them, but am not complaining about them because lot of people like them, also I was expecting futas in this game, which goes to my first point, that the author should say what kind of kinks the players should expect in their games.
So that if there is NTR planned, the people who don't like NTR can ignore the game.
