I really tried hard to like this drama because Gong Yoo was so handsome and sexy here, both as a nerdy doctor and a cool 18yr old student. His acting was amazing too especially when he confronted his father in EP 12 or 13, his acting was superb. My score 9 is for him. And even though Lee Min Jung is really beautiful, she can act, she can cry, she is cute, but I am not convinced with her acting, she looked more of an easy, gullible lady for me in the series. She's nothing but a pretty face (sorry,that is how i felt) And although Gong Yoo was handsome and all, I can not fall in love with his character as Kang Kyung-joon, how can he boast about his looks to GIl Da Ran while it was not his face in the first place. I like him better as, Seo Yoon-jae, I mean, how can Gil Da Ran, just forget about him, who by the way was lying in the hospital inside a different body. A doctor who loves kids, a handsome doctor being chased by his fellow doctor but still managed to be faithful. Who was on his way to tell confess his feeling to you before he got into an accident, being in a comma after saving the guy, who happens to enjoy his handsome face and sexy body, only to find out that Gil Da Ran chose that Oh-Oh school boy?? I mean,,,what duh??? But again if you long to see Gong Yoo in his early 30s go ahead and watch this. You might like it, since some people do. , But,,, I really did not like the story. I still love Gong Yoo though! Handsome!
