The game has some decent scenes, but suspension of disbelief is impossible, because the main character is so dumb and the situations she gets herself in are often extremely unlikely (the massage class at school, or the "casino" scene, for instance). There are no meaningful choices yet, so the game consists of watching the MC get into increasingly implausible dilemmas with the resultant implausible (but generally "hot") h-scenes. You can't even feel sorry for the MC because she is so dumb.
The game does do a good job of making sure you know what to do next, so that's a plus. Map designs are also decent (though the school appears to have only three classrooms and maybe a dozen students). The models are pretty well-done (except Henry, who looks like a serial killer).
I'd argue that the game could be excellent if this is just the most corrupt plotline and the author planned to come back and add choices once he gets all the way through one plot line, but this would still not be believable. Pretty much every character is a sociopath, and the story doesn't explain why. Maybe aliens?
