I'm currently doing a Manga Reading Challenged, and I stumbled in Watashitachi no Shiawase na Jikan, who can be translated to a manga very psychological and kinda dark in terms of mood and spiritual state. In this few amount of pages we can be mentally touched by a lot of terms like suicide, murder, accidents, violence and rape. The story starts a little bit confusing, where you don't understand where the story fits, but as the plot starts to happen, it's easy to understand. The last chapter was hard to read, cause it brings a lot of feelings to the surface. After reading it I understood why is so well placed in ranking.
