Everyone should read this now. So far it's only up to vol 7 in english scanlations, but they go up to vol 10 in if you can read chinese (me: painstakingly, but I want to know what happens so bad).
I should start off by saying the art is beautiful. Sometimes Natsume's eyes are a little too big for my liking, but other than that, I really like how the characters are drawn. Then again, it could be a like-it-or-you-don't scenario.
The female protangonist is unlike the normal shoujo females we come across. Yes, she's extremely pretty but other than that, she's a normal girl with her own thoughts that often jump between naivety and maturity. Things aren't always the way they seem and Natsume deals with those issues as realistically as you'd expect her to. Like someone else said, don't be thrown off by their age. Asakura started drawing them young for a reason. This manga really digs into the less-rosy aspects of being young and looking at things the way they are.
Kyou is always throwing me and Natsume off. He's a kid with a big responsibility and practically walks around like a star of the village, and naturally gains everyone's attention, especially Natsume. Without giving anything away, he's the character I have to rack my brains over the hardest. At first, it's crazy - the things he does and says - but when revealed, his human qualities are the most poignant. He is, after all, just a boy.
All in all, one can't help relating to this story, all of its painful, tender and joyful moments.
Drawbacks: Reading in chinese is making my brain hurt. If you're the type who can only read English, and like to read the whole series at one go, you might want to wait till it's completed scanlating.
I'm really into slice-of-life genres. I'm not saying this manga is extremely slow, because it does proceed at a pace I'm not tearing my hair over. However, it IS set at a rural village and Natsume spends a lot of her time wandering to the beach, so expect some scenes of the sea and flowers. Again, the art is spectacular.
