i like their casting,main character lee jongi and moon chae won..i love them and story  has nice phase and I like this drama ... I don't know about original so i I don't want to compare it ....from my point of view their acting  is  like professinal and I like  it ....After this  OST higher plane and another day is awesome  i can't understand  the lyrics  but i like the beat of the song..overall i like it  the cases  and suspense scenes..between the bonding of team  and their scene is  awesome and I  want to give a chance for another season.....
