Review based on entire series
I have mixed feelings in regards to this manga. It's kind of hard to enjoy a story when you dislike one of the characters. I couldn't bring myself to like anything about Kyoujima. His behaviour, and attitude, just didn't do it for me. Nor did the weak-willed Togawa, to be honest - I like my semes with some manners, and my ukes with a little spunk.
The other two stories lacked substance for me. I hate it when the ukes are too weak to fight back and basically end up being violated. I was kind of disappointed with them. The only real thing which kept my attention was the artwork.
