This was the drama that kickstarted my addiction. I wasnt into kdrama that much back then although Kim Rae Won, who I thought was adorable in Attic Cat and My Little Bride, and Park Shin Hye, who is insanely famous in our country, are two names that I remember. The chemistry they had in this series was really good and not to mention that I am partial to age gap and teacher-student stories. I must admit that the main story did drag on a bit. The pacing noticeably slowed down as the main plot had to give way for the patients' stories to be shown. But while waiting for the main plot to develop, I was rewarded with the discovery of great actors such as Kim Min Suk and of course, Nam Gung Min whose guest appearance was so amazing it broke my heart. There are other supporting and guest performances worth mentioning in this series but I think KMS topped the list. The OST in this drama was pretty good too. I wasnt into kpop but while watching this series, No Way kept playing in my mind that I had to download it.
