I love this manga.
A collection of short stories revolving around the "Girlfriend" theme, the mangaka obviously isn't aiming to develop any sort of characters or story here and it's great like this.
What I love about it is that for fucking once in fiction, the guys are not portrayed as the bad guys in the relationship, instead most of the time they are the victim.
I loved the way the whole stereotypical boy/girl power relationships were completely ignored and shows a side of life that people don't often know or talk about.
It really touched me this manga did.
The art is amazing too, although the breathtaking art only appears at the beginning of each chapter, usually depicting the girl. It is used nicely to intro the characters, and works well to make u feel drawn to this Pretty girl, as if you were in the shoes of the guy that is focused on.
But if your gonna read this just to fap, don't bother, it's not aimed for that and you will be disappointed if you think otherwise.
It's a powerful sentiment for any guy who has ever felt unfairly treated in their relationship, or been hurt by someone they love. An issue that is rarely addressed, over looked by the typical boy hurts girl scenario. The mangaka has done well to show this, even though it is true that it is exaggerated in some ways, but I think this is justified for his thoughts to be conveyed properly.
