What starts as a single night quickly spirals into a covert series of rendezvous. The film skillfully juxtaposes the bright, polished world of Joon‑ho’s corporate life with the gritty, intimate spaces where the affair unfolds—rooftop bars, quiet back alleys, and late‑night diners. Their connection deepens as they share personal histories: Joon‑ho’s childhood longing for approval, Mi‑ra’s fear of being abandoned. Their secret meetings become both an escape and a mirror reflecting their deepest insecurities.

The affair’s secrecy begins to erode both protagonists. Joon‑ho’s wife, Eun‑ji , senses his emotional distance, while Mi‑ra’s estranged brother, Sang‑ho , shows up unexpectedly, demanding financial help. Meanwhile, a nosy coworker starts piecing together Joon‑ho’s unusual absences, increasing the tension.
