Brother, NTR is like shit, I have seen works that upset people's psychology. NTR is when another character steals the main character's woman. This is the most basic explanation, although I hate it, I have to admit as a hypocrite that I love Netori, Netori is the "main character" stealing someone else's woman. And this game is the best Netori game you will ever see, without any NTR in it. Go and play you won't regret it
