This drama gets to the heart of why some people are driven to help others. What makes a doctor yearn to heal a patient? The visual animations of an acupuncture needle penetrating the skin and charging the blood with healing life are amazing! This drama explores the Eastern medicine vs. Western medicine, while giving us interesting characters, time travel, romance, "fish-out-of-water," humor, and a little bit of history. I fell in love with Kim Nam-Gil and his ability to portray a multi-faceted character. I finished this and immediately rewatched it. The music is great, too.
