I'm rating this drama 10+, it' so perfect up to the last minute of this last episode. Even though of so much twist coming all the way in each episode, there were so many revelations keep on poping up which is related to the previous incidents happened 20 years ago. Black is perfect for Song Seung Hoon, he's daebak here and I also want to congratulate Go Ah Ra, she improved her acting a lot here. Congratulatios to all the staffs and crews as well as to all the actors that gives life to all the characters here, a very job well done. And to the screenplay writer, you almost make my brain burst out from my head to keep on remembering all the names of the characters involved in this drama. Satisfied for the ending, in order to make Ha Ram safe and happy, there is Leo by her side up to her last breathe in order to meet Black at the end. Once again, kudos everyone ??????. Hoping to have this kind of story soon coz I love this genre.
