A very entertaining and hearth-warming manga. Somehow it resembles shoujo manga, but it's worth reading every chapter.
Character descriptions and development are somehow lacking, since the author decided to take the "easy path", and the core of the manga can be contained in no more than 10 chapters. No deep stories, side plots or wicked developments (the main plot does not offer much room to that anyway). Still, the remaining ones are full of gags and funny situations, and the reading is easy.
What makes this manga really interesting is the balance between romance and comedy.
I would change the tags and categories, btw. Ecchi tag is somehow exaggerated, you won't find more than a bunch of inocent panty shots and a nipple showing. And so is the "multiple relationships" one, it would be better to say multiple crushes...
I've been reading manga for quite some time, so I'll give it a 7, but that by no means implies lack of quality, on the contrary. Very simple in form and style, so I decided to deduct some points.
