This was an absolutely outstanding drama. Ji Sung took acting to a new level. Every emotion was delivered superbly. I do hope he got rewards for his performance. 3 Superb actors working together. I laughed at the beginning so much then it became intense and they cried buckets. Omega's character was creepy but he did a great job. Oh Ri is always a treat to watch. She is a comedic star. Loved her in 'She was Pretty' with Omega. South Korea produces some magnificent actors. This drama was in a class of it's own. Loved it and highly recommend it.
