Absolutely wonderful! Delivers and then some!
Love the two leads, especially Uhm Tae Goo. I just read that he's won a few awards in films and it shows in his performance. Perfect casting as his looks aren't very conventional and his voice is reminiscent of Marlon Brando in The Godfather. (I also like that we almost never see him in that awful hairstyle with the forehead hidden by bangs or whatever that every Kdrama romantic lead seems to be contractually forced into in the romantic scenes, ew). Han Sunhwa is an amazing contrast to the ML's gruffness without going over the top ridiculous. Love all the characters and how the main cast are more mature than we're used to in romantic comedy.

Also, someone give an award to whoever directed and choreographed the fight scenes and the car chase! I'm really tired of the stylised fighting in dramaland. The fast, brutal pace is much more realistic and effective in getting a response.
