Character Arc
Lee Tang begins the series as a passive, unmotivated college student with little sense of direction, working part-time jobs and feeling largely invisible. His ordinariness is central to the story, because it makes the violent turn his life takes feel both shocking and unsettlingly plausible. After a fateful late-night confrontation, he is forced to confront the consequences of an act he did not plan.
As events unfold, Lee Tang grapples with a disturbing pattern and the suspicion that the people caught up in these incidents had committed serious wrongs of their own. The series uses his internal conflict to explore guilt, denial, and self-justification. He is not portrayed as a confident antihero so much as a frightened young man trying to make sense of what is happening to him and whether he bears moral responsibility.
Across the season his arc becomes a study in conscience under pressure. Choi Woo-shik plays him with a jittery, watchful quality, leaning into the character's anxiety rather than menace, so that the audience is constantly asked to judge him while never feeling fully comfortable doing so. His relationship with the manipulative Roh Bin and his cat-and-mouse evasion of Detective Jang sharpen the central question of whether he is a vigilante, a victim of circumstance, or something in between.
