Thank you, and you don't need to worry. I have zero plans and zero desire to have the love interests hook up with other characters (except for other females who are also options for the MC's lovers) - the girls won't be cheating on the MC, the MC will not be offering them to other guys like sharing a bottle of whiskey.
I was considering having prostitutes available at some points/places - this was an earlier idea, and there are much more important character relationships to present, not sure if I am going to do this, or if I still want to, but if so, it will be optional.
The one more likely possibility is giving the MC the option to become sexually/romantically involved with a higher being who (at least technically in the real world mythologies) has a significant other.
I welcome the feedback on any of these possibilities, and I will certainly consider such player feelings in my decisions. Ultimately, I am going to create this the way it speaks to me, but I am still interested in and care about how the players feel.
Regarding NTR and other sexual situations, based on some developer discussions I've read, the perception of it really being a part of game can vary from whether it involves the MC, whether it is optional, whether it happens at all with other characters who have absolutely no intimate connection to the MC, or any other scenario I am failing to think of. Please feel free to clarify your perspective on any of these areas, as I would love to have a better insight into how players perceive the various possibilities, especially as they relate to what I create.
But on the simpler side of things, I have absolutely no plans on any of the MC's love interests cheating on him, nor for the MC to offer them up like candy to someone else. The closest possibility of NTR that involves the MC is having the option of being with a woman who has a significant other, is not a "fall in love" love interest, and/or is a higher being.
I realize that some situations are very disliked by some people. For example, a couple of posts back when someone opted out of playing L&P because the story may very well show some level of femdom, even though it does not involve the MC, and wouldn't actually be a sex scene but part of the surroundings or an important part of a character the MC may meet. I do plan to include optional femdom involving the MC, but it is not a priority at this point, nor is this game meant to be a femdom focused game.
There will certainly be displays of tragic events (and I might consider giving a warning and option to skip viewing them, as I've seen done in The Deluca Family), but I have no interest in the MC's significant others sneaking around on him, nor in him offering them like they mean nothing to him.
Edit: I am not always on discord, but I do check in frequently, and it is a good place more detailed back and forth discussions of things if you like. Still happy to answer questions, concerns, whatnot here, but just wanted to mention the discord option if you are interested in it.
