Roh Bin is a sharp, tech-savvy young man who becomes fascinated by Lee Tang and inserts himself into the unfolding events. Part observer and part manipulator, he positions himself as an ally to Lee Tang while pursuing an agenda of his own, and his presence destabilizes the story by making it unclear whether he is helping, exploiting, or testing the protagonist.
His role deepens the moral murkiness at the center of the series. Roh Bin appears to share, or at least understand, the rationale that the people harmed had done wrong, and he uses his skills to shape how events play out. This makes him a key figure in the question of vigilantism the show keeps raising, complicating any simple reading of who is responsible for what happens.
Kim Yo-han, a former idol who transitioned into acting, brings a slippery charisma to Roh Bin that keeps both Lee Tang and the audience off balance. The character functions as a foil and a wildcard, and his evolving relationship with Lee Tang is one of the season's central dynamics, raising the stakes of the cat-and-mouse chase with Detective Jang.
