His ability is Sixth Sense, which manifests as various senses that provide advice about his surroundings: Extrasensory, Sensitivity, Intuition, Past, and Insight.

Extrasensory Perception appears very rarely, perhaps once or twice a year. It provides detailed, easy-to-understand, and significant hints about a scene. However, because it brings in too much information, Deokgae usually endures immense pain while it speaks and collapses as soon as the case is resolved.

Sensitivity uses short, blunt speech like a frightened child, speaking of survival instincts and paranoia. It mainly reacts in dark or dangerous-looking places and is most sensitive to the fear of others.

Intuition has a cheerful personality and uses casual, friendly speech. It shares instant judgments and impressions of appearances. Because it describes physical features, it often points out places that can be interacted with through the five senses, though it sometimes makes judgments that differ from reality.

Past uses a formal yet archaic tone and short sentences, speaking of hunches and things beyond what is currently visible. Among the four, it is the only one that uses ancient words or pure Korean terms rarely used today. Fitting its name, it often speaks of memories from Deokgae's childhood that he himself cannot remember.

Insight uses very formal, polite speech (Hapsyo-che). It speaks metaphorically about the full story of an incident or conveys anxiety and interpretations of the situation. It gives the impression of narrating Deokgae's current state.

Deokgae is usually startled whenever these senses appear. He refers to Sensitivity as 'Sensitivity', Insight as 'Insight', Intuition as 'Intuition', and Past as 'Past'. Extrasensory is never mentioned by name.

These senses give very vague hints that are impossible for Deokgae to understand through his own logic.

He is Jung Gongryong's junior partner and views Gongryong as someone who is always joking around and slacking off. In reality, however, Gongryong cares for Deokgae the most and treats him quite well.

He has beige hair and white eyes, and is frequently told he is handsome.

He gets most annoyed when Gongryong plays pranks or slacks off (though he doesn't cross the line, it's mostly grumbling).

He is a Police Corporal with 5 years of experience.
