I understand your point about NTR, I don't like it either, but, hey, here comes a but, the name of the game is Stay Strong or lose, but rest assured all NTR content can be avoided, and even more so not all characters will have this content, and I mean more this will affect the story of the game, so even for those who like the theme, I think you should avoid it, because the consequences are different.
Of the 28 female characters already planned for the game, 8 of them will NEVER have NTR content, trying to follow this route with them will generate a lot of problems, even the game over with some of them or their death.
This is a topic that worries me, I don't want to draw this kind of thing, but if you don't have it, the game loses a little of what it's supposed to be, you stay strong so that no one tries to steal what is yours.
