Great manga. I cant really tell why, but it felt natural. Even though the setting is weird, it felt completly believable.
I wish i could understand the meaning behind the story, and maybe I unknowingly do and that's why i'm loving it.
Dont know why it's considered a shonen tho. It's obviously a seinen. The story of a guy who's comitting suicide out of despair, and then out of love, isnt really a story for kids.
