After OCN 'Trap' I was so looking forward to another suspense thriller twisting exciting crime drama, Lo and behold, it was terrible, it started well then confusion because of too many names to place, the children numbered & killed?, 'your father wants to kill you..', thus begins the puzzle board. Many asked if Seul Gi is the daughter of ML/KSooHyun -- how was that possible? Yes some viewers commented .. ah .. its the 'cloning', 'insemination', 'organs for sale' etc..., it still left some plot holes & pieces of puzzles to fill in & not making any sense. Why do one create a story of protagonist & the antagonist with family ties?, like sending the adopted daughter to a 'police academy', i mean won't she hunt you down 'the father' for these unforgivable sinful crimes later on in life? Clearly she would have suspected the father had some connections to all those killed already but did not take action, come on you are a great 'detective' ! It became draggy & boring after the first half. Glad it was just 12 episodes to finish. Overall, fairly poor production and after reading on Wiki the CEO of the production was accused of embezzlement & taken over. Maybe that's why? The end part was stupid as well. Why sent in the 'swat' to the scene & pumped in so many bullets at ML? Why the overkill? Still no answer what the 'blue eyes' is about. Nationwide this drama was rated very low. Hope there is a better OCN drama production coming up.
