Biggest thing that I liked about it is the female MC is usually pretty cute (aside from a handful of weird renders). And I do have a weakness for switching multiple protagonist POV games in this genre. I love female protag games, and this is the best of both worlds. (As you can probably tell from my two games.)
Story-wise, I like that there are a few actually different paths, like the "revenge" path when she catches the male MC cheating. I like that she has a few different options for cheating. (I always think it's kinda funny that many of these games, when they do the multiple protagonist pov, tend to give the male MC more potential love interests than the female MC, as if there was a world where that would happen!!)
There are places where it is not always executed perfectly, but I like the attempt.
Also, you have to give extra points to any game who manages to produce content without abandoning the game for as long as it has. This one may actually get an ending, which is amazing!
