While the description calls this an NTR focused game if you go 0 naughty score pure vanilla it makes for a pretty sweet romance.
I got several paths going right now and if I had to rank them it would be:
Soft-Sharing - I like hotwife/swinging but holy fuck Martin is the worst person imaginable to do it with. He has zero respect for their marriage or boundaries and trys to rape her in her sleep if he is able. Get naughty score but reject options that physically involve Martin. Got good naughty scenes wife is clearly getting a little frustrated but still listens to MC.
Soft-Cheating - How deep can you get before you can't walk it back anymore? Starting down the cheating path but interupt Martin on the phone and then pick all the options to try to save the relationship. At the ending scene it looks like she is regretting the cheating she has already done so it would be awesome if this path lets you salvage things.
Vanilla - classic for a reason
Full-Sharing - Like top choice I like sharing but Martin really drags it down and I haven't enjoyed scenes with him so far.
Full-Cheating - Just the worst. The escalation makes no sense. Their relationship is fine? Seriously I don't get how over the course of 3 days she is seduced enough to fuck Martin in the shower with her husband right there and hardly seem remorseful. It's just too quick
don't even entertain that cuck shit
