“Your bed slammed the wall last night.”
The neighbor’s husband said it with a smile inside the morning elevator, and Minseo nearly dropped the trash bag in her hand. How did he know?
The Moments We Were Secretly Overheard
That night, Minseo asked her husband, Jaewon. “Yesterday… when we did it, did the neighbors hear us?”
No, not us—the sound that belonged only to the two of them had never left the room. Because the apartment walls were paper-thin, they had practiced sex that hovered near silence, swallowing even their own breaths.
But the neighbors were different. The rhythmic thud of their bed against the wall, the woman’s clipped moans, the man’s low laugh. They pretended not to hear. Yet inside Minseo’s skull the thud lingered, a pink bruise.
The Chemical Reaction His Words Set Off
From that day, Minseo began to watch the couple next door. Three in the afternoon—she opened the door at the exact same moment and met the husband’s eyes. The angle at which the tall man looked down at her. The fresh bite on his neck. His face carried a silent confession: I shook your bed.
Every time she peeled off her underwear in the bathroom, the thought slipped between her thighs: Could my body be shaken like that too?
The Five Centimeters Between Their Bedroom and Ours
Actually, Minseo had heard them once before. Six months earlier, a night she was home alone. The woman’s moans beyond the wall grew louder, then—suddenly—the man’s voice: “…Does Minseo-ssi make that much noise too?”
A single sentence slid down her ear canal and raised her temperature by 0.2 degrees. She pressed a speaker to the wall, ready to record. In the end she only listened.
Why That Sound Moved Me
No psychology textbook lists this: How to become aroused by the sounds of the couple next door. But we know anyway. The bedroom is meant to be the most private place, yet it is also the most fragile. Beyond the wall, an illusion that someone is whispering, Do it like us.
Minseo tried to shake the illusion, yet every time she had sex with Jaewon her ears sharpened. Not Could we be shaken? but Could we be heard?
Last Line
After that day, Minseo wondered whether to bolt the bed to the floor. What would you do—fix it in place, or turn the volume up?
