It’s about a strict, light-haired senior instructor who got demoted from the frontlines to train new recruits because he protected his squad instead of blindly following orders. He’s so harsh and yells so much that the recruits think he's a villain. To help him out, his dark-haired junior boyfriend visits his room at night and asks him to wear a standard Private's uniform for a roleplay scenario. Experiencing the other side makes the instructor self-conscious, and the next day he completely changes—speaking kindly to the recruits and patiently teaching them weapon handling.
