Was skeptical about it at the ending of V.3 with the seemingly forced NTR (whether we see it or not). In my opinion id say it only truly NTR if the player has had the option of forming a relationship (romantic or sexual) with a character, chosen too and then you witness them have sex with a different character. If youve already had the option to 'decline' them then i say its not really NTR at that point. Such as if you declined Chan and then saw her with Troy for example. But seeing how Seath has responded about the NTR being fully optional im optimistic as i love where this is going at the moment. Its convinced me to sign up as a Sub. Good job Dev!
