I started on this drama mainly because of Song Joong Ki since I've been a big fan of him ever since Sungkyunkwan Scandal. And I'm mighty glad I did. I was pleasantly surprised to find that without adhering to cliched Kdrama machinations or plot developments it was able to keep the viewer entertained throughout. The acting by the entire cast is honest and mind-blowingly good especially the 3 leads. The stories of the patients, their suffering and human moments moved me to tears at times. Although I feel a few of the guest stars or patients over-acted at times but that doesn't undermine the overall seriousness of the drama. Coming to the romance part, it was delicately portrayed. The development of the relationship between the leads and Hye Young's friendship with Jae Suk give the viewers some truly memorable moments.
