Joo Jin Mo is one of my favorites. In the role of Ji Eun Ho he demonstrated a greater acting range than I had seen in his other works. As a peevish, spoiled actor he still managed to be adorable. Kim Se Rang's performance as Eun Dong was good. Not sure if she had previous experience in a lead role but the portrayal as an amnesiac was believable. Although I found her romantic moments with JJM somewhat lacking. Perhaps her acting at these moments in the drama simply paled in comparison.to JJM. Supporting cast was excellent - Kim Yoo-ri in her usual role as a "B". Kim Tae-Hoon as the bad guy whho simply misunderstood. Score was poignant at just the right moments with great clarinet soul. Could have been one of the GREAT melodramas in KDrama Land except the ending fell totally and completely flat. Did the writers quit after Episode 14? Still one of the best of 2016. I have rewatched this twice already. If you like angst and yearning this one is for you!
