Hmm, I still don't know... wasn't the story about music? It felt kind of boring...
Something about singing... not the most exciting story lol. I wasn't really watching for the story anyway xD
Reminds me of when I watched Kono Danshi and don't remember a thing about that story, but it was hella pretty
That said, I'd kill for a bl manga to get animated that has a decent, memorable plot.
