I dont really know how to do it either, i know tha a serious review would talk about art, story and all these thing that are importante for a good manga
but for real, i just want to say how much a apreciated the experience, this damn manga made me laugh SO MANY TIMES, and made me cry EVEN MORE times.
And thats all that i need in a manga, something that make me experience all these emotions, thats what i call a good manga.
