One thing you should learn by watching this drama is, don't give ratings if it is not the end yet. Finale sucks. They just waste what they started. All 15 episodes are good enough. Not with episode 16. I think this is a loss to Park Bo Gum. Even the ratings in South Korea is very low. They should reconsider giving audiences a good ending. This is one of the worst Kdrama. Not recommended. The casts are great but the story flow flops. Don't watch this if you don't wish to waste your 16 hours of time, watch other KDRAMAs. To TVn, please make another good Drama. JTBC and KBS are rocking now. Your era has been gone.
