After watching these 12 episodes, It was disappointing. Honestly, I watched this drama just because of Kim So Hyun but end up there isn't enough acting from hers in this drama. So if you want to watch a drama which is from Kim so hyun, then I recommend (Who Are You, 2015) . Things I liked from this drama: -The idea on how the setting and storyline was set -It gives you a mysterious feeling (kind of thriller somehow) -If you like thriller types of drama than this is a good choice. Things that I disliked: -It would start to be a bit boring in the middle of the drama, cause it's kind of repeating the same action but just with different characters. -The drama doesn't make any sense for me -There isn't enough acting time for Kim so hyun and Lee min hyuk (BTOB) From my opinion, if you like either or both of the main role characters than give this drama a try!
