omg, Nana is my second favorite manga. It's awesome. Every time I read it, I always want to cry sooooo badly. I'm all like,"I luff you, Hachi!"
I love Takumi because he's super hot. But his pretty-ness makes him evil... They made Takumi really hot in the Live Action movies. Both of them are great. I cry every time I watch them.
The anime is pretty good too. I feel super cool. I was at my local Japanese market and the had the whole anime series for $10 on DVD, but with no English dubs. It helps me practice Japanese a bit, though.
I have also come to the conclusion that my best friend is the living Junko. She's way too similar to her. She also says that I'm the living Hachi.
