Summary from mangafox.
“Ever since I was a little girl, I’ve been infatuated with the “other side”; the world of splendor. Yes, I wanted to become one of those glittering stars. And so, my dream has come true. But now…All I want is to be beloved by someone.”

Octave is an yuri manga. It is a fairly realistic adult story. Good amount of drama is in it as well. The last chapter for volume 4 is out and it currently on-going. I have read an few yuri mangas and this one is actually quite good. I recommend checking this one out if anyone has time to do so.
