If you haven't read it, you need to read it! Skip Beat is probably one of my favorite manga at the moment. It's hilarious and the characters are so well-developed and have deeper motivations and problems than your average anime characters (imho).
The story follows Kyoko Mogami, a 16 year old girl who discovers her childhood friend, aspiring pop idol and boy she loves, Shou Fuwa, only keeps her around to act as a maid and earn money. Furious and heart broken she vows to get revenge by beating him in show business. (summary from wikipedia!)
Along the way, she also meets a pretty colorful cast of characters including the charismatic top actor in Japan, Ren Tsuruga.... who at first seems to hate her for no reason. But, we all know where that leads! Haha...
Anyways, I love this series. I just wish someone who knew Japanese or Chinese would get off their behinds and translate the two most recent chapters that have been out for at least two months... *bitterness* ... ahem..
So, who do you want Kyoko to end up with? My vote's for Ren, personally, but Shou is always going to be around to stir things up... I think Shou and Kyoko might be able to be friends again though. I imagine he may eventually write a song for her. :]
