Jul 15 2008 02:11 AM as i understood it, the anime was not classified as shonen-ai in japan, but when it was picked up and licensed in the US, they placed it in the category based on the fact that they had an openly gay character.
now i haven't really read the manga, but people and anime bloggers who have said that most of the story only has implied shonen-ai elements, but if you're expecting something like junjou romantica or gravitation, you're not going to get it. so far, my take on it is that it's more comedy/slice of life than yaoi.
