I mean this Manga is great but there are a lot of yaoi Mangas out there with good plot and great story and characters while this one in my opinion is 80% sex scenes so a can't imagine how the anime would be, I think they will make an anime to promote the Manga, they will do just one season then stop but the Manga will keep on going, for sails of course.
(anyway if that's the case they better not censore their sex seens )
Sales*
i think they are going to make an ova, so it will be dvd released. that way, they can make the sex scenes. just a guess though
More possible
I can't believe this is getting an anime (￣∇￣")
