I TOTALLY LOVED THIS DRAMA...
It was super smooth and healing. If you wish to take a brake from all those serious and emotional dramas , then this drama may help you. It made me laugh a lot , and the characters were all portrait in a positive way and that made this drama a better one.
Still talking about its negatives :
> The character Dr. YE needed a bit of development , actually a lot though .
> Dr. YE is one among the main leads and that means his feelings and thougths needs to be exposed to the public.
> Though he's a main lead his portions were no better than that of a supporting character. The director could have shown the reasons behind Dr. YE's behavior , his family and the reason behind his last work and his break up. And most importantly the something stage between the leads were not clear. It didn't clearly state Dr. YE's feeling towards the female lead at the starting episodes like how he fell for her and how he had a hard time to know and control his feelings.

In short my one and only problem is that DR. YE [played by LEE JOON HYUK] didn't have a character development by being a main lead while the supporting roles and even actors playing guest roles had the justification for their roles.
