Senior Lieutenant Choi Man-su
Senior Lieutenant Choi Man-su functions in the film not as the direct instigator of the incident but as a dramatic device that detonates the 'temporary peace' formed between soldiers of the two Koreas. He arrives in the final confrontation scene and in a single gesture converts the emotional current of 'human friendship' back into 'military confrontation.' His appearance symbolizes how easily — and how violently — ideological boundaries can be reasserted, maximizing the film's thematic intent.
Senior Lieutenant Choi Man-su: The Physical Embodiment of the Ideological Boundary
Senior Lieutenant Choi Man-su functions in the film not as the direct instigator of events but as a dramatic apparatus that destroys the 'temporary peace' formed between soldiers of the two Koreas. His existence is a reminder that no matter how much human exchange takes place within the Joint Security Area, there is no escaping the physical reality of fundamental ideological confrontation.
1. The Context of His Arrival: The Fracture of Peace
The film's narrative focuses on the process by which soldiers from North and South visit each other's guard posts, share drinks, and even take photographs together — building a relationship as 'friends.' This process grants the audience its greatest emotional release, planting the hope that the wall between the two Koreas might actually crumble.
At the very peak of this emotional crescendo, Senior Lieutenant Choi Man-su appears. In what feels like a frozen moment of peace, he draws a pistol and trains it on the others — bringing everything to a halt. His appearance is not merely a provocation. It is a visual shock that reveals how fragile everything they have built together truly is.
2. Analysis of His Actions: A Violent Reassertion
The climactic confrontation scene in which Choi Man-su appears is the film's climax. His actions are highly calculated, rooted not in emotion but in 'discipline' and 'the boundary.'
- Drawing the Pistol: He reaches for the pistol first, instantly pulling the situation out of the realm of dialogue and persuasion and into the realm of physical violence. This means the friendship built by both sides can still only communicate in the primal language of the gunshot.
- The Attack on Gyeong-pil: He turns to Gyeong-pil and demands, "Did you play around with puppet soldiers?" — then assaults him. This line brands their friendship as 'betrayal' and gives voice to the external gaze of ideology.
- The Pressure on Woo-jin: He then pressures Woo-jin to draw his own weapon, confining the entire situation within the frame of 'military threat.' His actions appear driven not by emotional turmoil but by the military mission of 'maintaining the boundary.'
3. Symbolic Meaning: The Irreversibility of Ideology
Senior Lieutenant Choi Man-su reverses the flow of the film's narrative. What he symbolizes is not the hopeful concept of 'reunification' or 'reconciliation,' but the cold reality of 'the boundary' and 'discipline.' His arrival poses the following questions:
- Humanity vs. Ideology: No matter how much human exchange takes place, how long can that friendship survive when confronted by the vast system of ideology?
- The Meaning of Space: The JSA is a neutral space, but Choi Man-su's appearance demonstrates that even this space can be violated by ideological tension at any moment.
Ultimately, Senior Lieutenant Choi Man-su can be read as a living ideological boundary line — the figure who most starkly illuminates the gap between the 'warm humanity' and 'cold reality' the film sets out to portray.
Why It Matters
Senior Lieutenant Choi Man-su is not a simple villain or conflict catalyst. He symbolizes the essential difficulty of the theme of 'division' that the film addresses. The film emphasizes 'the emotions native to human beings' through the friendship between the soldiers, but his arrival hammers home the cold reality that no matter how intense those emotions are, breaking through the enormous wall of 'ideological structure' is nearly impossible. His existence returns the momentary emotion the audience has felt through the film to 'the weight of reality,' completing the work's deep tragic quality.

Sophie (Major Sophie Jean)
Major Sophie Jean bears the narrative axis of this film. She is a Swiss Army major serving with the Neutral Nations Supervisory Commission, with the background of being Korean-mixed — a complex identity that places her as an 'outsider' belonging to neither camp, providing the legal and psychological foundation to pursue only the objective truth of the incident.

Gyeong-pil
Oh Gyeong-pil is one of the most emotionally complex characters in the film. A seasoned professional who has lived as a military instructor across many countries for more than a decade, he initially keeps the world at arm's length — revealing little emotion to either Soo-hyeok on the South Korean side or to his superiors. This initial reserve reflects the military environment and ideological formation he has lived within.
