Yes. We said “characters,” because we are describing interactions involving the main character and multiple female characters. That is literally the context of the sentence.
Sure, if someone wants to argue pure semantics or wording clarity, fine. Maybe we could have worded it even more directly than we already did. But the overall point itself was never ambiguous on our side:
If we say there is no NTR, then there is no NTR.
The female interests in the game revolve around the main character exclusively. There are no routes where love interests pursue other men, no cheating against the player, no sharing scenarios, and no content fitting stereotypical NTR themes.
The aftermath wording simply refers to continuation or consequences of scenes involving the protagonist himself and the female character involved with him. Nothing more.
And to be completely fair here, if there is any “technical” angle someone could stretch into an NTR-adjacent category, it would only be the fact that the main character himself can become involved with a woman already trapped in an arranged marriage. Meaning the protagonist is the one committing the act, not being cheated on.
But based on your posts, it is pretty obvious which kind of NTR you are actually concerned about, and we can say with complete certainty: there is no such content here, and there never will be.
