Chapter Text
The silence of Apartment 602 was never truly silent. It was filled with the rhythmic hum of the refrigerator, the distant, muffled rush of city traffic six floors below, and the soft, rhythmic breathing of a four-year-old girl asleep in the next room.
Seokjin sat at the kitchen island, his chin resting heavily in the palm of his hand. The clock on the microwave glowed a harsh, neon green: 11:42 PM. In front of him sat a lukewarm cup of chamomile tea he’d forgotten to drink and a stack of colorful plastic folders from Somi’s preschool that needed signing.
He was tired. It was a deep, bone-settling kind of exhaustion that sleep couldn’t quite fix anymore. For three years, it had just been the two of them. He had learned how to braid hair without pulling, how to soothe night terrors with a low hum, and how to balance a corporate budget while calculating the exact amount of milk left in the carton. He was doing a good job. Everyone told him so.
But sometimes, in the dead of night when the apartment felt too big and his shoulders felt too small, the weight of being everything to someone pressed down on his chest until it ached. He was twenty-eight, but his joints felt heavy, and his heart felt strangely hollow, like a house built for a family that had never moved in.
Suddenly, a low, deep rumble vibrated through the floorboards.
Seokjin didn't flinch; he was used to it by now. It was the midnight return of the motorcycle. He listened as the heavy engine growled into the building’s underground parking garage, the bass of the exhaust rattling faintly against his kitchen windowpanes before cutting out entirely.
Floor Three, Seokjin thought idly, his eyes tracing the beige pattern of the linoleum floor.
He didn’t know the guy's name. No one did, really. In the building’s crowded, overly dramatic group chat, the rider was simply referred to as "the menace in 304." The gossip from the older ladies on the fifth floor was predictable. They claimed he worked at a rough-around-the-edges repair shop down by the docks. They whispered about the dark ink that stretched across his skin and the heavy leather jackets he wore even when the spring air turned mild.
Trouble, the building manager had muttered in the lobby last week. The kind of kid who doesn't care about rules.
Seokjin hadn't joined the conversation. He didn't care about neighborhood gossip, nor did he have the luxury of time to worry about a stranger's reputation. His only real grievance was the volume of that engine. Yet, as he sat alone in the dim kitchen, listening to the final, echoing echo of the bike disappearing into the concrete belly of the building, a strange, uninvited thought crossed his mind.
The guy always came home late. Always alone.
Seokjin wondered if the apartment on the third floor felt as empty as the one on the sixth.
Sighing, Seokjin poured the cold tea down the sink, the ceramic clinking loudly in the quiet space. He checked the deadbolt on the front door, smoothed down the wrinkles in his slacks for the next day, and finally slipped into bed. He closed his eyes, pulling the duvet up to his chin, and let the familiar, aching yearning of a solitary life carry him into a restless sleep.
The next morning was a predictable storm of missing velcro shoes, spilled apple juice, and the frantic scramble to get out the door by 8:00 AM.
"Somi-ah, hold Daddy’s hand," Seokjin pleaded, juggling his leather briefcase, a tiny pink backpack adorned with cartoon penguins, and his car keys between his fingers.
Somi, her dark hair tied into two slightly uneven pigtails, giggled and grabbed his index finger. Her small light-up sneakers clicked happily against the hallway tile as they hurried toward the elevator bank.
Seokjin pressed the down button, leaning his head back against the cool wall for a brief second. His eyes burned from lack of sleep. If they caught the traffic lights right, he’d make his 8:30 morning presentation by the skin of his teeth. If not, he’d be apologizing to his supervisor while wiping dried strawberry puree off his sleeve.
The elevator chimed, the metal doors sliding open to reveal an empty, mirror-lined car. Seokjin ushered Somi inside, turning to press the button for the lobby.
As the doors began to slide shut, Seokjin caught a whiff of the air left behind from whoever had used the elevator just minutes before. It was a faint, lingering scent—completely out of place for a sterile apartment building. It smelled of rain, sharp metallic grease, and something deeply grounded, like cedarwood.
He looked down at the floor tracker as it lit up. 5... 4...
The scent was heavy, almost tangible, clinging to the small enclosed space. It was a ghost of a presence, a reminder that while Seokjin felt entirely isolated in his little bubble on the sixth floor, there were other lives pulsing just beneath his feet.
"Daddy," Somi piped up, tugging on his hand as she pointed at the corner of the elevator floor. "Look. A shiny."
Seokjin blinked, looking down. Left behind in the corner was a small, heavy silver metal washer—the kind used for locking bolts on machinery. It was smudged with a streak of dark grease.
"Don't touch it, sweetie, it's dirty," Seokjin said softly, gently pulling her back.
He stared at the tiny piece of hardware as the elevator bumped to a halt at the lobby floor. It was a silly, inconsequential thing, but as the doors opened to the bustling, bright world outside, Seokjin found himself thinking of the midnight rumble from the night before.
He stepped out into the morning rush, the heavy glass doors of the lobby swinging shut behind him, completely unaware of how small the distance between the floors was about to become.
