I was able to see why this drama won multiple awards.It was well written, the cast were A+ actors and actresses, and all sorts of emotions were conveyed effectively.I'm a new fan of Korean dramas (an IU fan) and I can say that this is the best role Lee Ji Eun ever portrayed so far.
This drama has many lessons and values to teach about life in general.Its simple yet effective storytelling will make viewers hooked.
Give it a try! You are missing something great if you haven't watched it yet. :)
