Curiosity as to why this drama sparked a Korean wave in early 2000's not just in Asia but globally made me watch this. A few episodes in and I got hooked as well. Bae Yong-joon, who plays the male lead, is utterly charming; Choi Ji Woo, who plays the female lead, is truly one of the most beautiful Korean actresses I've seen. They, and other cast members, played their roles with passion and sincerity. The story is engrossing and the OST is stirring.
