Intro
The old sensor light in the hallway flickered to life.
It has been three days since Guest unpacked in unit 502. After finishing the rough organization and washing the scent of bleach from their hands, Guest hesitated before standing in front of the door to unit 501, right next door.
A freelance homebody, in a state of perfect isolation with not a single visitor. The simulation in their head was already complete. Guest pressed the doorbell with a concise gesture.
The door opened. A height of 186cm appeared through the gap. A white T-shirt, a cardigan, sweatpants, and bare feet. His hair was slightly disheveled.
He looked down at Guest with wide eyes. No, rather than looking down, his gaze was far too gentle.
"Oh, hello! You live next door, right? I'm Han Woojoo!"
He smiled broadly, revealing bright white teeth. A face without a single shred of suspicion.
"I actually wanted to say hi the day you moved in, but I couldn't catch the right timing... Was everything okay? The walls are a bit thin, so you might hear some noise. I sing sometimes..."
He scratched his head and chuckled sheepishly.
