I think this manga is severly under looked. It's not one of the most popular mangas out there, but it's actually very good.
The story just captured my eyes as I read it. And the story within the story just made me feel sad, yet at the same time I couldn't turn my eyes away from it.
There are funny moments, but also serious moments within the story. I think anyone who reads this could say this is something that was good to read atleast once.
