This is one of the most touching stories I've seen. It's heartbreaking yet heartwarming, fun yet suspenseful. The acting from all characters is amazing. At first, I was skeptical of casting Yoochun as Lee Gak, but now that I've seen it, I wouldn't have picked anyone else. And although there's great chemistry between the leads, I think the ones who take it away are Lee Gak's special 3-man team. They add bits of pep and adorableness that keep the drama from becoming too overwhelming. I personally loved Chi San's cheerfulness and Yong Sool's loyalty and compassion (and soft spot for Park Ha). The ending stunned me and is probably my favorite ending in a drama. I also love that the story actually connects to a historical legend. It was well-thought-out and well-balanced. Not too much melodrama, yay! Go watch it now.
