Plot
Jang Jae-young (Park Seo-ham) is the star of the visual design department — tall, model-like, and effortlessly charismatic. Chu Sang-woo (Park Jae-chan), a top student in mechanical engineering, is logical, precise, and a bit of a loner. When a group project goes south, Sang-woo outs freeloaders during his presentation, causing Jae-young to unexpectedly delay his graduation.
Instead of holding a grudge, Jae-young becomes fascinated by this rigid, calculating junior who stands in stark contrast to his own free-spirited nature. As the two are forced to collaborate on a mobile game project, sparks fly — first as friction, then as attraction.
Jae-young is like the sun: bold, magnetic, and guided by his heart, shaped by a supportive upbringing and unwavering self-belief. Sang-woo is like a computer: deliberate, data-driven, and solitary, shaped by an environment that rewarded control over spontaneity. Working together forces both to face the “semantic errors” in their own lives — moments of vulnerability and unpredictability they can’t code around.
Through late-night work sessions, subtle provocations, and unspoken care, the boundary between rivalry and romance dissolves. The movie smooths the series’ episodic pacing, giving their journey a more fluid rhythm while keeping all the emotional beats intact.

💬 My Take
The film version of Semantic Error feels cleaner and more emotionally satisfying than the series — less like a set of chapters, more like a complete romance. Jae-young’s portrayal here is even more confident and determined than his series counterpart, willing to shoulder responsibility for both his and Sang-woo’s future. Sang-woo’s transformation is more understated but equally compelling: his guarded world slowly invaded by Jae-young’s warmth and persistence.
The chemistry between Park Seo-ham and Park Jae-chan is the core of this story — from teasing provocations to tender gestures that reveal care beneath the bickering. Height difference, skin tone contrast, and costume symbolism (notably Jae-young’s use of red, Sang-woo’s “YES!” shirt, and visual callbacks like the vegetable-man doodle) add layers for detail-hungry fans.
And of course, the joy of this enemies-to-lovers romance is in the “pull and push”: calculated distance, accidental closeness, and a final resolution that feels earned. Love here is not a flawless algorithm — it’s the one bug you refuse to fix because it makes the system perfect.
