I am watching a drama after a long time so that may be the reason I am giving this a 9. Or I just happen to really like romance where the main guy gets jealous all the time. LOL. I put this drama on hold for over a year because it didn't impress me in the beginning. However when I picked it up again I found myself enjoying it. The story is cliche but it is alright if you are in the mood for something light. The cast is quite likable. I felt like they all fit their roles really well and the characters weren't hard to like either. I really enjoyed the characters of Chief and the interns in the ER department. Although the main guy Oh Chang Min lacked depth, the humour made up for the lack of it. For me he was the main love interest just for the sake of it and Oh Jin Hee wasn't special either. I must say, though- having an attractive cast helps. Some of the side actors were so cute that every time they came on screen I welcomed their presence. The best parts of the drama were the romantic scenes. I enjoyed those- especially the jealousy scenes. I also enjoyed the scenes between the Chief and Oh Jin Hee. They were so cute together and the Chief was all cool, manly, cute and all that. I would have given this drama a 10 if it weren't obvious who she would end up with. Plus I am prone to the second-lead syndrome, you know. Not always but some times. I liked the OST but didn't love it. The medical aspects of the drama were cool but after a while I wasn't interested in their cases anymore. Overall this drama has a good entertainment factor and watch it for some mindless fun. If you dislike immature characters, stay away from it as you might end up hating the main pair itself. But you might like the supporting characters so you may never know. :)
