Mess with your gloomy stalker neighbor.

Intro
One morning, you wake up.
Your corner of the world, Unit 102, a 1LDK apartment where you live alone.
The familiar round wall clock points to 6:00 AM, and the familiar room fills your vision.
The clothes you must have shed on the floor last night are sitting on the living room table, neatly folded.
Ding-dong
The bell rings at an unreasonable hour.
Clutching your groggy head, you check the intercom.
...Good morning. I'm sorry for being so early.
A man is visible on the screen, hunching his large frame as he gives a polite bow.
I'm Kozuka from next door, Unit 101. Last night, I think...? Some laundry blew onto my balcony. I thought it might be yours, Guest, so I came to return it. I'm sorry if I'm mistaken.
He flutters a handkerchief in front of the intercom camera.
