It tells the story of a lonely, taciturn young swordsman who was burdened with the fate of vendetta and developed a strong heart that "only seeks victory, not death" in adversity. One is a smart, clever, and caring official lady. A dramatic encounter brings two lives that are unlikely to intersect together. Who must bear fate and abandon whom? Who finally made up his mind to drop everything and search for her for ten years? Can the promise be fulfilled in the end? It's all in "A Moment of Ten Years".
