It's a short series, since it only ran within one year, with 4 volumes in total. It's actually titled Prétear - The New Legend of Snow White, which I only learned when I was browsing it through (answers.com)

I was able to see the anime version of it first, and thought that it was the typical magical girl show, with the costume changes and magical powers and being surrounded by a harem of good-looking young guys.

The anime and manga version of it differ somewhat, both in characters and plot, though unlike some of the manga-anime I've recently read/watched, I actually like the anime better than the manga in some respects, due to certain story elements being different, especially in Sasame's case...

I shall leave it to you to discover what these differences are, since if you're interested enough, you'd be curious enough to check it out for yourself.
Anyway, despite the "snow white" in the title, the story isn't exactly 100% "Snow White: The Fairy Tale"-inspired. Well, ok, there are the SIX (they're missing one though to complete the seven :P) cute guys (not dwarves) and the Pretear(sort-of snow white), and you have the "evil" stepmother, and the stepsisters (annoying/obnoxious, and cold/distant), and the "kiss", but the meat of the plot is of course different.

I actually like the fact that this story is character-driven, in that it focuses on the different personal issues and experiences of the characters, even the villain of the story has their side (as to why they're became the way they were), explained. Though not all of their back stories are given (since it's a short series anyway).

For some reason, Hayate (Wind Leafe Knight), kind of reminds me of Tamahome (Suzaku Seishi from Fushigi Yuugi). It must be the hair or something...lol
Well, I enjoyed reading/watching this because some of the characters' questions and thoughts are stuff I've thought through and pondered on as well. Sasame (whom I like, actually), in the manga sort of answered a bit of what I had been asking myself in the past rather well.

Even if you're not looking for the answer to the meaning of life, Pretear will be a good read.
