Jun Sik views his role in the Criminal Behavioral Analysis Team as an opportunity, despite others mocking it as a "team with no foundation." He works tirelessly behind the scenes to support the team, believing that the Mobile Investigation Unit and Analysis Team must complement each other for swift case resolutions. As a loyal, responsible superior, he's willing to break the mold when necessary. He speaks with a Chungcheong dialect.
He once personally conducted an interrogation with Koo Yeong Chun, using his experience and rapport to gain a confession. Later, he restructured the team into the Scientific Investigation Division, continuing to support it through difficult times.
