Nana

This is the best anime I've seen in my life period. Probably because it is close at heart for me. About music,sex and love, the characters have really realistic personality. Every episode is engaging with it's storyline and soundtrack. If you have a weak heart, you will cry watching this anime. And also one of the main reasons why this anime is the best is that it's about rock and roll.The only downside this anime has is that almost every character smokes, haha. they made it look so cool. I urge you guys to really catch this. Really awesome.
