The characters are all done well but are pretty typical of harem-type series (Suwami's a very nicely done ojou-sama tsundere and is my favorite of the main cast). The lead male character however sticks out somewhat because he's not the typical wussy male you find in these kinds of series, so that's kinda nice. The humor is pretty well-done and the chapters so far have all been very short standalone stories with nice conclusions (you can actually read the chapters all out of order and still enjoy it). The art is simple, but it works very well for this kind of series.

Overall, it's very cute and could stand well enough on its own without any embellishments like fanservice, but in the end what really sticks out about the series is how strangely overt the nudity is. The series actually shows the female characters' "downstairs area" anatomically correctly and completely uncovered (or mostly uncovered) nearly every chapter! And the characters are all in middle school! It blows my mind that the series can even be published legally.

But yeah, cute series with fanservice that shows way more than most other series. Take that as you will.
