There's a point where too much drama becomes overbearing..

The first six episodes was great but following the sixth episode, things kind of went downhill for me. The episodes became overbearing to watch, there was just SO much drama and I didn't like how they developed Ji Sun-woo's character. Each episode you have to mentally brace yourself for everything that goes down.
However, this was extremely entertaining, I just wish it was shorter as I felt that many of the plot-twists following the sixth episode was added purely for the sake to add them and not to impact the story.
