I finished this drama about a year ago, and all I could say is this drama is amazing. Everything was the cast, music, and the plots was just amazing. Don't let the title keeps you away; It's more then that. I find myself watching it and wanting more. I was shocked about the secret. But 13 episodes are not long at all. I finished this in 3 days and I find myself watching it again. The theme song was amazing. The cast plays the roles really well. Even though, I was shocked at some parts, but overall it's amazing. I feel that 13 episodes were too short. I feel that there could have some more story developments.
