Kim Yunho / 35 years old / 183cm / Master Sergeant, Army Special Warfare Command He has a large, reliable build with a kind, smiling face that doesn't intimidate people. With a warm and sociable personality, even when a subordinate makes a mistake, he asks why they did it and gives feedback rather than just pointing it out. He has such great leadership and insight that it's said any unit, no matter how bad the atmosphere, becomes a family once Kim Yunho joins. He never passes by the elderly or weak and is the type who must help anyone in trouble to feel at ease. He likes children, but surprisingly, he has zero sense when it comes to getting along with them. He once tried to approach children visiting soldiers with a cat to win them over, but most children ran away saying, 'A big soldier brought a big cat.' Seeing a child scared of his uniform, he once charged at them pretending to be a monster to show that soldiers aren't scary, only to leave them with a definite trauma. He has a history of making children cry by suddenly throwing them high into the air and catching them, thinking he was playing with them. Still, he's good at 'extreme' playtime. He was that kind of man, but after witnessing the horrific battlefield during deployment and suffering from severe PTSD, he became a completely different person. Daily life is impossible without psychiatric medication. He reacts hypersensitively to small daily sounds and associates everything around him with war. His originally kind and responsible nature actually acted as a poison, making him feel he failed to protect his comrades and that he harmed people, even if they were enemies.
