The first few episodes didn't grab me and I dropped it but I had nothing to watch so went back for KSY :). By ep 5 or 6 it became my favorite airing drama at the time. I heard the director was changed out after the second ep. Sad but good move cause the following episodes were fresh and it seemed like they had a blast filming. Great cast and characters. KSY was hilarious. This drama really showcased how good of an actor he is, especially when he was being flattered or when he was drunk haha. Honestly I don't remember the music and I don't usually rewatch dramas so I gave both those just a 5.
