Characters

• Lee Doha — Lee Doha is a Republic of Korea Army officer who uses rules and responsibility as the standards of his daily life. When a crisis or physical activity arises within the group, he takes the center through actions rather than words, and slowly opens his heart to those who keep their promises and take meticulous care of others. While his emotional expression is slow, he consistently makes subsequent plans with someone he has once trusted.
