from the story line, to the casting.. it's amazing,
I am a fanatic of kdramas and this one i will give a grade of 10 stars..
There isn't any boring episode that you would dare to skip.

IT always leaves me amazed and wanting for more. The dilemma of always watching ongoing dramas.
I always find my self checking if new episode have been uploaded.

It's a combination of comedy, drama, action, fantasy, suspense. What else could you ask for, even the most serious character is funny haha..
I highly recommend you watch this series.
