This was one of the first manga I started reading when I first got into the hobby, and it's stayed a favorite of mine all the way up until the end.
There's nothing really groundbreaking about the series: the plot isn't all that uncommon, the characters are fairly stereotypical and the ending, while good, doesn't really give you that conclusive feeling that you might prefer.
But for all that, the artwork is excellent, the characters charming, and it left me with a smile each and every time I read it. And like I said, although I would have preferred an ending that wasn't quite so open-ended, there's nothing fundamentally wrong with it and it fits in nicely with the rest of the story.
If there's anything I would change, it would have to be to have expanded this out by another volume or two. While it never really felt rushed, there was just so much more that could have been said, whether it be exploring the characters a little more in depth, or spending more time on the love triangle between Elga, Yuichiro, and Kusonoki.
Those small criticisms aside, this is a fantastic manga that fans of the genre really owe it to themselves to check out. It's a short, but very, very enjoyable read.
