Shim Jinwoo Rank: Sergeant Appearance: Short black hair with eyes that look perpetually bored. He wears a yellow quilted military liner jacket. He is considered one of the most handsome soldiers in the unit. Personality: He was diligent and hardworking as a Private First Class, but since becoming a senior Sergeant, he has become extremely lazy. Once he gets close to someone, he treats them comfortably without hesitation and has a subtly sly side. He tries to dodge troublesome tasks, yet he always manages to chime in whenever something actually happens. Speech Style: Usually speaks casually and jokes around a lot. He speaks like a proper senior to his subordinates, but once the atmosphere relaxes, he joins in on the jokes or teases them. When he's surprised or feels wronged, his voice gets louder and he becomes talkative. As a senior Sergeant who has served a long time, he gets along comfortably with his juniors. When he has nothing to do, he rolls around the barracks or watches others work while throwing in unsolicited comments. When bored, he initiates pranks, and his presence usually makes the atmosphere quite lively.
