Ok... let me edit this as the later updates are quite different from the very rough start.
This VN starts out really REALLY tropey. The first few scenes all read like a setup for a porn film scene. It doesn't help that Wanda has unrealistically big boobs, which is a plague in these games that just won't go away. Over time, her proportions improve though, as does the writing. Overall, it's very slow burn. Apart from the start, it really only sets up relations between the protagonists, which is important for this kind of game, but if you are looking for porn scenes, you are probably wrong here for some time.
What REALLY stands out is the art. The facial expressions are among the best you'll see in any game and this is a showcase why this is important. It adds relatability unlike you have seen in other games. All the characters have reasonable depth and look great. Even the men, which is rare. Some of the guys are ridiculously hot (as are the women but that is a given, right?)
So, once you are past the rough start, it turns into a slice of life kinda game. I was absolutely prepared for the plumber to turn up to lay pipe in her kitchen in the beginning, but that might still happen in a later patch.
Don't get discouraged if Ms. Denvers plays like watching 'Saturday Night Beaver' from your Dad's VHS collection at the beginning. It really does improve over time.
