By far my absolute favorite drama! I have never posted a review b/c I hadn't found a K-Drama that didn't lack something with the ending! I was starting to think that these writers had no idea how to end a drama. Then I watched this show... It had everything: mystery, suspense, drama, romance, comedy, and even a little bit of action. And they did a phenomenal job w/ the finale! All of the actors did an AWESOME job! Shin Sung-Rok, who played Lee Jae-Kyung (psycho brother) did a FANTASTIC job!
