tl;dr: A manga that is amusing in an ecchi way and has a solid set up and reasonably solid conclusion, but lacks a middle strong enough to give them both any deeper impact.

This manga sets up somewhat of an overarching plot, though really it doesn't matter all that much at all. The character set up is decent enough as well I suppose, though there's no development or anything like that either. Rather, the focus seems to be on simply having amusing episodes with the various characters. And to that end, I think it's pretty good, in that I think it was pretty solid comedy and amusement wise, with the art definitely helping in that regard, though it should be noted it goes about this in quite the perverted manner. However, the plot and character development does feel kind of important contrary to what you'd expect, and this is one of those mangas where the substantial portion of that is supposed to be in the middle, as the set up occurs at the beginning and can't really go all in really doing all that much, and the ending tries to give some sort of overall plot resolution so it doesn't have time to really dive into it that much either. The problem here is that the manga was too short for there really be a middle, and with it basically reaching it's finale right as soon as the opening felt over, I don't think that it ever really hit the good part that much. Still, for as short as it was, I thought it was decent. The art as mentioned was pretty good and used well.
