It was a while ago I read it as far as I remember it was pretty good. Good characters, beautiful art, interesting, kinda angsty and more bloody and serious than most other shoujo. Kinda tragic as well. There was a heart throbbing love triangle but unfortunately I thought it didn't really get resolved very well. I really rooted for the white haired guy! I think the main weakness is the ending which felt messy and rushed. I heard there is a sequel though so I'll probably check it out.
