Yaoi Manga?

I'm looking for a yaoi manga that I read in the past, please forgive me as my recollection of it is kind of scattered. All I know is that the couple are classmates, and that the uke is commonly referred to as "Sparkly-kun" by other students. Also, at some point in the manga, their class decides to run a host club as part of a school event. I don't remember if they were already together at the start of the manga or if they hook up as the story progresses, but I think it may have been the latter. Also, there is a second couple in the manga, and the seme of that couple happened to be in love with the uke (Sparkly-kun) from the first couple, but after Sparkly-kun is taken by someone else, he gets together with his friend who had all the while been harboring feelings for him, but had kept them hidden because he knew that his friend was in love with Sparkly-kun. Please help me out if you can, it would be greatly appreciated!
