Really have to say that I am not a fan of this series. I have two friends who absolutely love it, and both are big manga readers whose opinions I respect and appreciate, but for me, this series just completely missed the mark. There was nothing original about it, and having read Wallflower, I was really disappointed with how much Sawako seems to be a carbon copy of the Sunako from Wallflower, even down to the nickname. The difference? Wallflower's lead female is much more interesting, not so mousy, and Wallflower has a better storyline, in my opinion.
I think this would be a great series for people who haven't read a lot of shojo already. The art is good but if you've ever read any manga that's about a shy girl who likes a boy, you're not likely to find too much that's new here.
