Great drama, it has romance, comedy, and medial surgeries. I loved watching all the different types of emergency's that would come up dealing with the heart and the patients themselves could touch you and make you care for them. The romance was good, I'm surprised I liked it actually b/c I'm not to fond of the main actress but she did a pretty good job on this drama portraying Hye Suk - she first comes off snobby and ambitious, haughty and arrogant but Eun Sung (the country bumpkin) rubs off on her and slowly chases away the cold wind in her heart. Their comradeire was really nice to watch, growing on each other from totally different viewpoints and coming to accept each other. Eun Sung (Ji Sung) was often labeled the "idiot" b/c he didn't graduate from Kwang Hee University, so he'd get looked down upon quite a lot but eventually the doctors and residents came to accept him and the fact that he really isn't an "idiot". I thought Eun Sung and Kang Gook (Jo Jae Hyeon) were a lot alike - they both cared for the patients and sincerely wanted to save them - even if it meant going against authority. They were my two favorite characters. The comedy was delivered by both Ji Sung and Park Chul Min :P They'd have me giggling by just the little things they did. The guest appearance by Lee Ji Hoon - or maybe I should say supporting role - since he appeared in more than half the drama - he was sweet in his pursuit of Hye Suk and touching as a patient. I loved every scene he was in ^^ And little Kim Yoo Jung appeared toward the end of the drama as a patient and she touched my heart. Music was great - I especially loved 2 songs - "Thanks" by Hong Kyung Min & "Bye Bye Bye" by Park Il Re-watch value - it's good for a re-watch but I don't know if I will re-watch it anytime soon. If you're looking for more than just a medical drama - then this is the one for you, yes there are plenty of medical surgeries but there is a great balance of romance too. ^^
