Boku no Futatsu no Tsubasa, isn't a bad manga, it's just a manga that needed more time. I personally believe with more chapters it would have been a bit better. The story pretty much is a basic teenage "growing pains" with a twist. Of course, with any teen manga, sex is sure to follow (and i mean alot of it). It starts off well, good laughs, nice story. It's just the ending of the manga, that feels like it was written in two seconds that makes it bad.
