Depends on what you mean exactly?
Will the MC be NTRed?
-No, based on the game it's being remade from there was no scenario you as the MC are the victim.
Will the MC have relations with women that are married and basically fall in love or lust with him over the course of the game?
-Again, based on the old game yes, also the teacher in the demo is married.
Hope that helps
I mean the main protag was a shota in the last version and now he is not, the amount of games that start without NTR and it gets added years later is quite big, so I don't know why would you trust any developer here, specially one that has (as far as I remember) a ntr game. Just adding my two cents, no one should be shocked or pissed if NTR becomes a thing later down the line.
Edit.: Also to make it clear, Nergal saying he won't add doesn't really mean a lot, first this is the internet and second other devs made the same promise in the past, my point is just be ready when a dev makes a radical change in their games, is common practice here.
