I thought we had a topic about this before, but I guess it disappered somewhere. I'm recreating this, it's really recent and really good too. The whole plot isn't confusing, but everything within it is. But please give this drama a try. It can be found on veoh and crunchyroll. Though I'm not sure about youtube and dailymotion.
Some info thanks to dramawiki.
