Story- Very different from most stereotypical K Dramas. It incorporates pretty much all the genres which consited of comedy, action, romance, music themed. The pace is good but some episodes did feel longer than others. The ending was cute and one of the best endings in a drama ever! Acting/Cast- Hyun Bin and Ha Ji Won had excellent chemistry even though they are complete opposites. The supporting cast was fantastic! Music- Beautiful score & OST. rewatch- because there are a ton of funny moments & the cast is just awesome, Id watch this once a year. Overall- This drama is the best korean drama ever made!
