If you came here because someone recommended you this drama, they probably will tell you how original and climatic this drama was. I was stuck on my chair watching this drama the whole time because of how every minute was so captivating and the cliff-hangers in the drama - OH MY GOD i hated waiting one week for the next episodes because of how good the cliff-hangers are after each episodes. i love the sci-fi concept behind it and its a very original plot that keeps you wanting for me, definitely recommended if you're looking for a thriller kdrama with a good love line.
This was acutally the drama that made me fall in love with lee jong suk!! Both lee jong suk and han hyo joo portrayed their characters very well + the kiss scene in the police station was my favourite scene it was sooo good HAHAHA
