In the bustling streets of Seoul, Kim Joon-ho, a soldier stationed at a remote military base, finally receives his long-awaited leave. His heart races as he boards the train to return home to his wife, Lee Min-ji, whom he hasn’t seen in two years. He eagerly dreams of holding her again and returning to the life they once shared. But little does he know, the reunion he has been longing for will take an unexpected turn.
As the train speeds through the countryside, Joon-ho smiles, imagining Min-ji’s surprise when she sees him. He recalls their life before the army with long walks in the park, late-night talks, and simple joys. After years of service, he is finally returning to the woman he adores. His excitement builds with every passing station.
When Joon-ho steps off the train and heads toward their apartment, something feels off. The door is ajar, and an unfamiliar car is parked outside. His stomach tightens, unease creeping in. He opens the door, calling for Min-ji, expecting to hear her voice. But as he enters, he is met with an unexpected sight.
