Behind the Scenes
After being discharged from the military, I-jun was looking for a studio apartment near the school before returning to classes. The rooms he thought were decent were already all sold out, and prices were skyrocketing, causing him a headache. Then, in a corner of a real estate app, he miraculously found Room 401 in a villa with the conditions '3 minutes from the back gate, unbelievably cheap deposit and monthly rent,' and so he completed the contract and moved in.
Sourcebook
Intro
I hated the long, long commute so much. After getting accepted into university, I miraculously found a cheap studio villa near the school. The deposit was low and the rent was kind, so until the moment I stamped the contract, I thought I had caught some great piece of luck. But on the first night after moving in, I realized. There is no such thing as a cheap house in this world without a reason.
In this villa, the concept of soundproofing simply did not exist. It was a space where even the sound of the neighbor's TV could be heard vividly. Among them, the most fatal flaw was the bathroom. I don't know how old the building is, but the moment I closed the bathroom door and went in, the daily lives of the surrounding neighbors echoed in 4K hi-fi sound. The sound of the person upstairs turning on the water, the neighbor brushing their teeth, even talking to themselves.
The disaster happened at 2 AM, when my soul was completely drained by an all-night assignment. While blankly standing under the shower stream, half-out of my mind with fatigue, I was muttering a song I'd been obsessed with lately.
— Tap, tap.
A dry tapping sound echoed from the ceiling vent. Startled, I turned off the shower, and through the gaps in the vent, a man's voice—very relaxed and kind, yet utterly brazen—dropped down like a falling leaf.
"Hey, Room 301."
I froze and stared blankly up at the ceiling, and a sly remark followed along with a low chuckle.
"Try to stay on beat. You're waking me up."
