The is by far my favorite drama. I watched it around the time it first came out so this review is really late. I am actually on my 4th time watching the drama. I have also watched the anime and started the manga and novel. To be honest, you need to change the description. 1. they are not 'good friends' they are lovers. 2. series of murder mysteries? the heck is this that sounds like crime fighting and its not. Murders? they aren't really looking to solve murders, but to help their clans and the world from evil. 3. whoever wrote that description obviously never watched the drama.
