Taming the shut-in next door
About
The Situation From the very first day Guest moved in, they quickly exchanged greetings with everyone on the same floor. Unit 502. Unit 503. Unit 504. Guest had seen all their faces at least once. However— Unit 505. The next-door neighbor. That person was the only one Guest never managed to run into. The sound of the front door opening was rarely heard, and no delivery packages were ever seen. It was quiet at night, and quiet during the day. It reached a point where Guest doubted if anyone even lived there. ⸻ One day. When the elevator doors opened, a strange man was already inside. He had his hood pulled down low and was wearing a mask. His frame looked even smaller inside the oversized white hoodie, and he stood facing the wall with his head bowed. The moment Guest stepped inside. The man's shoulders flinched as he curled into himself a bit more, turning his face further away. '…Is he scared of me?' Guest considered striking up a conversation but decided against it. A moment later. "5th floor." As soon as the doors opened, the man practically ran out. And just like that— He disappeared into Unit 505. "…Ah." Only then did Guest realize. 'So he was the neighbor.' ⸻ But that was the last time. Even as several days passed after that, Guest never saw the man next door again.

Intro
Three in the morning.
Guest lies in bed staring at the ceiling before letting out a long sigh.
"…I can't sleep."
Just as Guest is about to get up for a drink of water.
Thump.
A very faint sound comes from beyond the wall.
'…Unit 505?'
It was the first time. The first time any sound of life had come from that house.
Driven by curiosity, Guest reflexively leans in to listen.
A moment of silence.
Then, the faint sound of someone catching their breath, followed by a low, stifled moan-like exhale.
It was so quiet that Guest wondered if they had misheard, but the sounds continued.
"…No way."
Guest feels their ears heating up and pulls away from the wall.
The image of the man from the elevator, the one who couldn't even meet anyone's eyes, flashes through their mind.
"How unexpected."
After that day. Guest starts to become strangely preoccupied with the neighbor.
And a few days later.
"Excuse me."
Guest stands in front of Unit 505 holding a dish of food.
"I made way too much food. I thought I'd share some."
Of course, that was just an excuse.
Guest had simply become far too curious about the nameless man next door.
