This drama was not one of the typical Korean dramas. It was a psychological thriller series and I really admired the acting of Ji Sung. He is one of the best actor and one can't differentiate whether he is acting or not. He becomes the character and he gives us what we wants. The sole reason I watched this drama was because of male leading actor. Though I was first annoyed by female lead at times, Ji Sung took over the stage. He overshadowed everyone. It is not easy job for anyone to act 7 different roles. If not Ji Sung who can do that? If you watch this drama all you will see is Ji Sung and will fall in love with him
