This is one of the most memorable Korean movie of all time for me. It offers a good balance of humor, thrill and heart. What I like the most is the fact that this movie is not just for the sake of executing a written script. STORY As far as I have watched Korean movies, the story is not cliche. Set in the past, it gives the audience a nostalgic feeling. With a lovable heroine and innocent hero, the story was well balanced. The villain is driven by jealousy which is familiar with Korean audience but the way it was executed was excellent (especially the resolution). Some might not like the ending, but I definitely loved it. With the hero's character overcoming all the struggles just to fulfill his promise, it was superb. ACTING I love Song Joong Ki. He gave Chul Soo a color no other actor could give. It's not easy to standout in a film with a very few lines yet he managed to do so. Park Bo Young's acting was heartfelt. REWATCH VALUE Definitely must re-watch.
