The story is not out of the ordinary. However there was enough angst to keep me watching. The ending was a little too open ended for my liking. The acting was exceptional because all the characters made me feel thier pain. Special shout out goes to Lee Kyu Han for his ability to portray a nice guy who can quickly change into a scary dude. I really liked him in smile you too. I want him in a starring role where he actually gets the girl though! I first seen Eric in Spy Myung Wol. I have to say I liked him in QSS even though he is a jerk for most of the time. He is starting to grow on me. The music is hip and also emotional so it really went well with the scenes. Rewatch value is low because the plot was not special enough for me to want to watch again. Overall this drama is very good but was missing some things to make it spectacular...
