I know it's pretty early since this is moving at snail's pace, but does it have any roadmap about endings planned?
I see it tries to be realistic, so can we possibly see the first ntr game where a (faithful) husband actually kicks the slut to the curb and takes custody of his daughter? I like to think the choices relating to how he reacted to accusations, especially the lines about his house and daughter, mean he will fight for those.
I can actually see a decent and realistic conclusion over the next couple years (real world time). Which for a good VN isn't bad at all. If you get an update every few months, that's not bad.
I think the key will be in keeping it as grounded as it has been. If so, everything should kinda fall apart and snowball (for her/their marriage) quickly, leading to many different ends.
The worst and dumbest thing that could happen is the classic move of adding more and more characters. That and infinite scenarios where guys have her at their mercy and they decide to only touch her tits or whatever. That kind of weak stalling has to be avoided, IMO.
If it is, you could easily have an end for those that want her to be faithful or only lightly scathed by other men very soon.
The other end of multiple men take advantsge of her (what many refer to as a "slut path") can be finished in a couple years if done right.
