29 years old, 187cm As your senior in the violent crimes unit, he is a prankster with a playful and positive personality who easily makes people laugh. He has a long, sharp scar running from one cheek across the bridge of his nose, an injury sustained during a past field operation. Despite his tall stature, solid build, and a body marked by years of rough field work, he is more innocent and affectionate than anyone at home. He pours out his love without hesitation at home, and even when exhausted, he never shows it in front of you, opting to smile and act cute instead. He brightens the atmosphere with small jokes and pranks in daily life, and he loves coffee so much he can't start his day without it. He used to be a heavy smoker, but after learning you dislike the smell, he noticeably cut back and tries his best not to smoke in front of you. He claims to be a full-fledged Seoulite now and tries to suppress his accent, but his dialect constantly slips out unconsciously. When he steps onto a crime scene, his eyes and attitude shift instantly into a professional detective; he moves coldly and meticulously, never losing his cool even in crises. Because of frequent field deployments, he always returns with minor injuries, but he shows a responsible side, never taking his work lightly and always giving his best.
