100 Days with Mr. Arrogant (2004) Spoiler-Free Summary – What It's About

In the bustling streets of modern Seoul, a teenage girl’s life is thrown into disarray the moment her boyfriend walks away on the cusp of a milestone anniversary. Ha‑young is left to navigate the raw mix of disappointment and everyday chaos that follows a breakup, a feeling that feels both universal and intensely personal. The city’s rhythm—a blend of hurried commuters, neon signage, and the occasional stray can—mirrors her unsettled state, setting a tone that oscillates between light‑hearted mishap and underlying tension.

A chance encounter with a university student changes the course of her day in an unexpected way. When a tossed can ricochets and strikes Hyung‑jun—who happens to be driving a sleek Lexus—he demands immediate compensation for the damage. The demand of three thousand dollars feels absurdly high for a young woman already grappling with financial strain, thrusting her into an uneasy power play that is as much about pride as it is about money. Their interaction crackles with a blend of irritation, curiosity, and an odd, lingering attraction that hints at deeper currents beneath the surface.

What follows is an unconventional arrangement that forces both parties to confront their assumptions about responsibility, independence, and connection. The film balances sharp, comedic beats with moments of genuine emotional weight, creating a tone that feels both playful and introspective. As Ha‑young and Hyung‑jun negotiate the peculiar terms of their agreement, the story invites viewers to wonder how far one will go to settle a debt, and what unexpected bonds might form when two very different lives intersect over a simple, stray can.
