What Korean drama are you watching now?

i'm currently watching a new korean drama,starring Eric from Shinhwa.Strongest Chilwoo is KBS's latest sageuk drama after "Hong Gil Dong". Eric will play a lowly officer in a ??? (eui geum bu) (a court that handles crimes of treason) in the Joseon era, nondescript, not very smart and whose lifelong ambition is to become a mid-level officer. However when night falls, he transforms into the top assassin in an assassination organization, who metes out punishment to evildoers and gives justice where needed. This challenging role will see him play out a man with two vastly different characters..In my opinion the story has very interesting character development hence suggest you to watch this drama .
