To protect "children, beauties, and the elderly" and defend the peace of the land.
Character Arc
Starts as a mysterious, somewhat playful soldier who hides his trauma behind humor. Through his love for Mo-yeon, he learns to share the burden of his job rather than shielding her completely. He evolves from a soldier who follows orders to a leader who prioritizes moral justice above command, ultimately surviving 'death' to return to his love.

To save lives regardless of who the patient is, and to find a love that respects her values.
