Usually a big fan of NTR phone games, just something about them I really like, but this one doesnt have the best setup tbh. To be fair its very early in development and not much content here yet, but the "we are having marrige issues, go to a therapist and she tells us to try an open relationship" thing only really works with heavy porn logic in mind and here its even worse. Lets be real, if a marrige therapist said that the wife needs to go out and have fun and be free while the husband has to stay at home and watch, thats the end of the session bye bye therapist right there unless you drown it in silly amounts of porn logic. This sort of story only really works if the husband is a total whimp and a pushover and he doesnt come across as that in the texting, seem to hold his ground and disagree and be uncomfertable with the suggestion so it feels kinda weird when the story just barrels on and acts as if the husband is wrong in being sceptical.
A bit more build up, like the husband admiting he likes the idea or the usual "Try wearing some more reveiling outfits, go to a bar and flirt with a random guy and talk about how it made you both feel" kinda thing would do good before taking the plunge straight to talking about having sex with others.
The rest of the game is as you expect from AI art phone games. The writing itself is fine, the AI art looks good if you dont mind AI art and with some more chapters available this might yet turn into a good enough "Ye its porn logic delux, but its fun" experience.
