First of all, this game looks very good (I wanted to play it in rpgm but I left it for a while and better wait for it to come out), good job.
I don't want to sound like the majority who complain about the NTR, I only have 2 questions if it's not a problem:
1.- The ntr in this game is that you see girls who already have a partner (husband, boyfriend, etc.) having sex (this is not ntr since they are a couple) or is it a single girl that you pretend and another guy has sex with her without you liking that (this is ntr)?
2.- Is the game going to focus on this content or are they just some scenes scattered around the game (avoidable), I am not referring to a "path", but to some scenes in general?
It may be that this has already been explained in the original game but as I said I really could not see it in depth.
P.S. I know you are not the original game dev but I think you can more or less clarify my doubt
