The story is so gripping at the start, it's hard to stop watching.Then it started to get a little draggy towards the end. So much story from each characters, so I'm expecting constant development of their story. It is still a very good drama, good story with great acting skills, especially the bad characters (including the younger version casts), particularly Yeon Jin, who made you loathe her so much.I wish I waited until the complete episodes are available before watching, now the agony of waiting for season 2!
