As cited by his superior, Officer Park, he appears to pry too much into investigations. Dutiful and prone to skepticism, he has a predisposition for doubt and often second-guesses anything he is presented with. These traits proved to be detrimental as they cost him his position on the investigation team.Killing Stalking, Prologue / Episode Two Though relegated to the menial tasks of a patrolling officer, he retains these characteristics when confronting a potential house intruder. He also pauses when Park scolds him for mentioning the possibility of Sangwoo killing his own parents, showing he is either very sensitive or just is not use to be scolded.
Episode One — The Phantom Menace Edit
While out on patrol, he and Officer Park stop by Sangwoo's house when they find an unidentifiable boy standing outside the door.Killing Stalking, Prologue / Episode One Seungbae approaches him, and is told that he is a relative of Sangwoo. Seungbae bids him farewell, but lingers to watch. When he hears the house alarm announce that the incorrect pass-code has been submitted five times, he saunters towards the male, but the boy types in the correct pass-code at the last second and tells him goodbye before closing the door behind him. Officer Park drives himself and him back to the city, where Park finds Sangwoo with a girl. Sangwoo silently watches them converse before Sangwoo introduces himself to Seungbae. He reluctantly introduces himself in return and seems apprehensive as Sangwoo peers down at him momentarily. Park then mentions of Sangwoo's relative being over at his house, to which Sangwoo excuses himself to leave.
Episode Two — Attack of the Clones Edit
Officer Park comments on Seungbae being strange for a while since the encounter. Seungbae inquires of how Park's acquaintance with Sangwoo came to be. Seungbae expresses his suspicion on whether the case with Sangwoo's parents truly was a work of an outsider, noting the evidence of a break-in appeared as if planted, and on the possibility the murderer was Sangwoo.
