I honestly don't know why this show has got here recently such low ratings. Maybe some people tried to "mark" it as watched and rated basing on few episodes with poor or no translation.
Don't be fooled, even though I'm a guy I think this series is a gem. It's really really good if you give it a go. Im not that much into childish or girly things but this show I find to be soothing, relaxing and intriguing at the same time.
I highly recommend to anyone who wants to feel nostalgia of being a child, of first crush or of going to school. It's the best of this kind.
I've seen first 39 episodes, don't have it in english though. Such a shame no group picked this one up.
