The turning point occurs when Hyun-soo discovers Bruce Lee’s The Tao of Jeet Kune Do . The film visually emphasizes his reading sessions—close-ups of passages like "The usefulness of a cup is in its emptiness." Immediately after, Hyun-soo abandons formalities. In the pivotal rooftop fight, he does not bow, does not posture, and does not wait for the opponent to complete a ritual. He strikes first, strikes directly (to the throat, groin, knees), and ends the fight in seconds. This is pure JKD: intercepting the opponent’s intention, not blocking then countering. The film’s true antagonist is not any single bully but the "system" of high school itself—a classical mess of meaningless rules, seniority violence, and enforced humiliation. The principal’s office, the public canings, and the mandatory student uniforms symbolize fixed forms. Hyun-soo’s rebellion is JKD-like in that it does not create a new system (he does not form a rival gang) but rather un-creates the existing one through unpredictable, authentic action.
The Unchained Narrative: Jeet Kune Do as the Spirit of Rebellion in Once Upon a Time in High School Once Upon A Time In High School- The Spirit Of Jeet Kune Do
His famous final line—"I’m not your friend. And I’m not your enemy. I’m just your teacher."—is a Jeet Kune Do statement. It refuses the classical dichotomy (friend/enemy) and asserts a direct, functional relationship (teacher). This mirrors Lee’s famous phrase: "I do not hit, I am hit." Unlike Hollywood martial arts films, Once Upon a Time in High School refuses a triumphant ending. Hyun-soo wins the physical battles but is expelled. The school system reasserts itself. This reflects a core, often overlooked aspect of JKD: the spirit of directness is incompatible with institutional survival. Lee himself warned that JKD is not for everyone; it is a path for the solitary individual. Hyun-soo ends the film walking alone, leaving his friend and love interest behind. His victory is internal—he has unlearned fear and false respect. The external society remains corrupt. This tragic realism distinguishes the film from mere revenge fantasy. 6. Conclusion: The Spirit as a Living Metaphor Once Upon a Time in High School uses Jeet Kune Do not as a fighting method but as a philosophical blueprint for surviving authoritarian modernity. Hyun-soo’s journey from a rule-following soldier to a JKD practitioner is a metaphor for South Korea’s own struggle against dictatorship—a struggle that would culminate in the Gwangju Uprising (1980). The film suggests that liberation begins not with armies or ideologies, but with an individual’s decision to abandon the classical mess of obedience, to intercept oppression at its root, and to claim the direct, simple truth of one’s own body and will.
