Hello.
There is not and NEVER will be NTR in this game. There are a couple of extremely short scenes without very sexual content with secondary characters, they are characters that will not be LI's, but I only used them to contextualize the story and the motives of the antagonists. So, in short, there is not and NEVER will be NTR.
LI's will NEVER be touched by any man other than the MC.
