Respectfully it's in the tags for the game and in settings there is a check box which you can use to toggle NTRish scenes. So I mean really this is kinda a skill issue
It says "Optional NTR" in the tags, except it's not optional unless you have some crystal ball foresight and know where it happens to avoid it.
The toggle doesn't actually stop anything, the girl still gets groped when followed and fucked if you go to the wrong side of the map during a certain mission.
Unfortunately, it is not possible for me to plan around your personal definition of NTR.
I made a poll in the discord and the community decided that the images marked in the toggle are the ones that constitute as their personal definitions.
If I go by the largely accepted definition that NTR implies a romantic relationship with the protagonist first then NTR is not yet available in this game.
But neither of these definitions would satisfy you. If you have any other problems feel free to message me privately. I'd rather you didn't start arguments here.
