That stuff you have planned for later chapters isn't ntr right?
Before anything else: No. I do not intend to have any NTR in my game.
And I feel like the term NTR gets thrown around a lot for things that don't quite line up with it. This is only in response before anyone gets the wrong idea and is not directed at you lol, it just gives me a teaching moment that I will probably add this to the the Dev Notes section on the main post.
NTR Definition:
It describes a story or situation where someone's romantic partner is unfaithful or leaves them for someone else. The focus is on the emotional distress and humiliation of the person whose partner was "stolen".
In my games, I try to build on healthy monogamous and non-monogamous relationships as they are a center point of my own life outside of these games. Will there be sexual encounters that don't involve the main character at times? Sure, but they are communicated and agreed upon between the MC and all parties. If you as the player disagrees with it, they don't happen. The events can either be simply implied if they get the go ahead, while others, if the MC isn't there, can be from the perspective of one of the participating characters. If the MC is there, he will always participate.
I am a firm believer that you do not OWN another human being and they are free to fill their own lives with choices and experiences that they wish to have. The key part on that is everyone has to be in agreement and nobody gets hurt/or is intentionally left out of such activities.
Random info dump has come to a close haha...
