that is the problem with the game, people think it is an NTR game and in reality it is NETORASE, the only NTR there is in the endings for letting the girls have many sexual encounters with the hero.
But even these scenes are locked post game? I am 3 hours in and so far with everyone at chapter 3 and ...nothing really happened. For a H-Game there is surprisingly little to see as of now.
Edit: You need to see the 50 affection scene and effectly become a couple. Then the option unlocks with the tavern keeper......for being a NTS game which has the most content, the game does it's best not to communicate with the player on how to unlock it.
Yeah the game is a mixed bag. It takes too long for any good stuff to happen, it doesn't matter if you look for NTR or NTS stuff. Maybe it should have been better to start the game as an established couple. I dunno.
Coming from loving the older Avantgarde's games this was also not it....like their last 3-4 games.
Ever since the fox girls game they shifted their direction and start experimenting. Not to shit on to test out new things but all subsequent games were all just...meh imo.
