Well... this was... sort of meh... The art was pretty great, but it kind of failed to hit that well for me on account of the fact that the wife had about as much willpower as a wet tissue paper, and she was basically a total slut from the first second regardless of which part of the story you're looking at. She's incredibly dumb too... Like holy shit... so dumb...
I'll give the VN points for sticking to its guns and just giving the illusion that the cheating could be prevented for the most part, when in truth, the wife was already pretty much a complete slut before the trip even started.
Kind of a weird set-up overall...
Ultimately, not a terrible time waster, but also not something I'd care to revisit either.
