Rate- 10/10. This is one of the best medical drama ever. The chemistry between the cast is no joke. In every scene that they tried to save their patients, I always feel tense because it looks so real. This drama show the life as a doctor/surgeon that we might not know. I just knew about Yoo Yeon Sook from this drama and he's so good. This drama will bring you into roller coaster of emotion. If you guys love medical drama, watch this. You won't be disappointed. I don't really have the word to describe this drama because it's just WOW.
