True, there's no serious plot... It's as if the world was dedicated to "that". I really enjoyed them... Somehow (INTENSE!!! ) when I first read and went through the pages of the 4th story, I thought that it was the possessive guy who was intimidating and scary... Then I read the last page and thought that, "Wow...thanks to training, the other guy is more intimidating than him..." it's a new form of story and a strange depiction of love to me... But overall very interesting. I loved the guy with the camera at the last story...
HAHAHAHAHA....there is no plot to this manga at all...just sexy hot porn.
