I have registered in MAL right now just because I wanted to recommend this to the world. The idea of a calm and slow apocalypse that makes no violence and leads hummanity into the end of big urban centers is the greatest thing I saw in it. Although the manga doesn't seem to aim at criticizing modernity, it surely shows how life was happier before the massification of culture and impersonalization of things. It may sound stupid that the characters, which are mostly amazing, live their simple lives in the simplest way possible fiding happines in the simplest stuff, but the way it is shown reveals the simplicity I (and most of us) don't simply have. Not that I hate modern life, just that it's nice to at least dream of something different in the best suited genre for that idea: slice of life. If there's a potential that slice of life can live up to, that manga surely achieves the "simple hapiness" part of it
