I just finished this drama and now I don't know what to do with my life. This is one of THE best dramas I've seen in a long time. It was a drama that kept me hooked for all 20 episodes; none of the episodes felt like "filler" episodes or just to make the drama last for a certain number of episodes. I don't really write too many reviews, but I just have to let everyone know that YOU WILL NOT REGRET WATCHING THIS. I was on the edge of my seat for much of the time. Ji Chang Wook and Park Min Young had such good chemistry as a couple. I never thought I'd go so crazy just to see them hold hands! Music was great, too, and really the entire cast did an excellent job. 10 STARS!!
