[Jong-su], an aspiring young novelist, works a string of odd jobs around Seoul while chasing stories and trying to find his voice. One ordinary day, he crosses paths with Shin Hae-mi, a childhood neighbor and classmate, during a promotional event where he’s making a delivery. She has had plastic surgery, and she explains it with a casual honesty that unsettles him. He returns the pink watch he won at the promotion, a small token from their past that grows into something more tangled as they reconnect. Before long, she asks him to look after her cat, Boil, while she travels to Africa. Her departure is shadowed by a legal knot back home: Jong-su’s father, a cattle farmer in Paju, is caught up in a disagreeable dispute, pulling Jong-su away from the city and back to the land he once left behind.
Back at Hae-mi’s apartment, he receives detailed instructions about feeding the cat, and the two share a moment of intimacy that seems to anchor their fragile reemergence into each other’s lives. After she leaves, he dutifully tends to the cat, though he never actually sees the animal; he only encounters the litter box’s familiar signs. A solitary, almost voyeuristic habit settles in as he spends increasingly long stretches inside the apartment, finding himself drawn to solitary acts of self-quieting in a space that once belonged to someone else. Then Hae-mi calls from far away, revealing a harrowing turn: she’s stranded at Nairobi Airport for three days after a bombing near the city. She appears again, this time with Ben, a man she met and bonded with during the crisis, and together they embark on a night out.
During dinner, Hae-mi’s emotional vulnerability surfaces as she confesses a deep wish to disappear. The man with her, Ben, is wealthy and enigmatic; his work remains something of a mystery, and his aura of certainty contrasts with the insecurities that flicker across Hae-mi’s face. The setting shifts to Jong-su’s rural world when the trio travels to his farm. There, they share cannabis, and Hae-mi dances freely, even topless, in a moment that lingers with a wild, unguarded energy. After she falls asleep on the sofa, Ben reveals a disturbing hobby: every couple of months, he burns an abandoned greenhouse. He hints that another burning is imminent, close to Jong-su’s own neighborhood. When Jong-su confronts Hae-mi about her discomfort with being pursued by other men, she retreats into the night with Ben, leaving him with a troubling sense of treachery behind the glow of the greenhouse fires that never come to pass.
In the days that follow, Jong-su becomes consumed with watching the neighborhood, seeking any sign of a greenhouse burning. He is relentless, yet nothing materializes. Then a call from Hae-mi ends abruptly with a few seconds of ambiguous noises, and her number is disconnected. He cannot shake the fear that something has happened. He pleads with the landlady to let him into Hae-mi’s apartment, only to discover an eerie absence: the place is unnaturally clean, her suitcase sits as if she could return at any moment, yet the cat is gone. A mounting paranoia drives him to stake out Ben’s Gangnam residence and trail him to where he goes. When he spots Ben’s Porsche parked outside a restaurant, he follows the clue inside. Ben is with a young woman who apologizes for being late, and the three of them leave together. Jong-su presses for news of Hae-mi, but Ben—who cannot reveal much—admits he hasn’t heard from her either and suspects she may not have gone on a trip, noting that Jong-su was the only person she truly trusted, which awakens a strange jealousy in him.
A quiet, unsettling confrontation unfolds later when Ben invites Jong-su upstairs to his apartment. Ben presents a newly adopted cat and, while in the restroom, Jong-su discovers a pink watch tucked away in a drawer filled with other women’s jewelry. The discovery echoes the one Jong-su gave to Hae-mi, the watch that marked a past bond between them. The cat bolts out of the room, and the animal’s name—Boil—registers with a chilling resonance. Jong-su exits the scene without protest, leaving Ben to plead for him to stay.
The tension erupts when Jong-su requests a private meeting with Ben in the countryside, claiming to be with Hae-mi. Ben senses that she is not there. He asks Jong-su where she is, and in that moment Jo g-su’s resolve breaks; he stabs Ben to death. The act becomes a cold, deliberate act of violence, and the aftermath sees him dousing Ben’s car and body in gasoline, setting them alight. He tucks his blood-soaked clothes into the flames and staggers away, naked and shaken, toward his truck and the uncertain road ahead.
In the end, the story leaves a trail of unanswered questions, a stark meditation on desire, secrecy, and the explosive consequences of jealousy. The quiet, almost mundane textures of daily life—feedings, hotel-room intimacies, roadside encounters, and a farmer’s land—collide with a sudden, brutal act that reshapes every character’s future. The film lingers on the ambiguity of motive and the fragility of trust, inviting viewers to question what drives people to disappear, to burn, and to kill.
