For start , you must know that it's my first review so be gentle please. (few mistake will appear)
My review will be short. Notice that I write this in a subjective way.

You must read this manga. Why? Because, this manga can bring you a new/another vision of social life (or life in general) , and it's that's why this manga is amazing. I won't tell you what is this vision or how the manga puts it in place, all interest is in this.

You may not like it, but I am certain that it will affect you, in a positive or negative way. It's for me, the most important thing that a manga or an artwork in general, can bring to people.

Hope you will read this review without too much difficulty, bye bye.
