This anime was created by Ai Yazawa . I just started on it after watching "k" which is another anime I did a blurb about . I pretty much just mention it I didn't really talk about it. But so far as too watching 4 episodes of nana , I feel you could actually relate to this anime. It's really interesting and good to watch, if your looking for another anime to watch . P.s I cried at the ending "K". Also I'll start giving more info on who created the animes and on what it's about.
