The story line is okay, the mystery part is okayy, the setting is okayyy, the characters are okayyyy except that the LCY is truly a pretty girl to watch, but somehow it is still a drama worth to watch. In short what really makes me thrill about this drama wasn't the story line, mystery, the setting, nor the plot, but was the perfect teamwork and relationship between LDS and HJW, where you will wonder if you can achieve it with your partners or colleague in that way all the time. However, the story is still a little bit too draggy and to be honest sometimes will watch until fell asleep and couldnt bear to fast forward. Only if the drama is not that draggy it can be quite a perfect drama to me.
