I honestly couldn't tell if you were being sarcastic or not, so I'm going to answer as though you weren't.
This game doesn't really have NTR at all, which is why it doesn't have that tag. I will admit that sometimes it's just on a technicality and NTR haters will still dislike those scenes, but it's still not NTR.
Personally I don't like NTR. And yet I have no issue with this game, which says something.
All NTR sex scenes involving LIs are avoidable. The ones that aren't avoidable either happen before they're LI's or are flashbacks to before you knew them or, in the case of the doctor, aren't LIs at all (at least not yet).
The main exception to this would be Judy, but she's a prostitute, so you know what you're getting into with her. Plus, her quest is optional so that would count as avoidable NTR. Not that you see her having sex after meeting the MC, anyway.
And the only scene I'd say actually constitutes unavoidable NTR is in the Sacred Sex quest where the priest gets his dick sucked while performing the exorcism. Although you can join, which would make it swinging, not NTR.
So all in all, while there are plenty of scenes which are borderline NTR (and enough to piss off the most extreme NTR haters), there are none which are technically actually NTR.
