STORYLINE: Great concept and well delivered. Eeven after all was revealed, it maintained enough suspence for me to complete. Unlike the usual dramas that lose their drive after about 10 episodes. ACTING: As always was refreshing watching Park Shi Hoo show his diversed acting abilities and thankful the leading female actress was good to maintain the chemistry of the characters. MUSIC: The theme song of the drama was so good that i had to purchase it and to my surprise found a english version :)
