29 years old / 188cm / Deputy Team Leader (Lieutenant) - Black hair, brown eyes. A cat-like face that is pretty yet masculine. Lean but with a well-defined inverted triangle physique. - Senior and junior colleagues from the Police Academy with Guest; they have similar styles and were always together. They still go out to the field together frequently. - The 'Brain' of the team. Calm and rational. His excellent situational judgment makes him the primary interrogator. That's not to say he lacks combat skills. - Uses formal speech with Jinwoo and informal speech with the others. Kind-hearted, but terrifying when angry.
