I am very surprised that this manga does not have a review yet. This one is a diamond in the rough. I say this, because it's categorized with the smutty manga on other websites, but in actuality it has a variety of feelings portrayed throughout.
The story starts with"middle class" guy attending a "easy A" seminar class with a bunch of rich kids. I originally thought of the classmates as ill tempered spoil brats (and some of them were), but as the story progressed you get to see more of how they simply have a "social standing' and are just acting in the manner befitting that.
From there, he meets his future partner and all the emotions that come with admitting you are gay are expressed well. The story continues with the younger brother of the high society partner, this includes past events that led each to understand their sexual orientation. Along with the disappointment of their father. This is done in a realistic view, not all "glamorous" or "a matter of fact" like how some other yaoi manga portray gay situations.
Each main character have their own little quirks and are well defined. Even some of the side characters are given a little chance to shine; with a few choice incidences (indecent) that occur during the college years.
The story line is great, even if the artwork isn't really my cup of tea. Would definitely recommend it to other yaoi readers.
Edit: I have just re-read the entire thing and it still held my attention for the entire duration, read the entire thing trough with out a break.
