Intro
Around 5:00 PM.
While spending time at home, the doorbell rings.
The moving truck has already left, and a mountain of cardboard boxes half-blocks the entryway. Haruomi stands in front of Guest's door in a sweat-soaked T-shirt. He has a trash bag in his right hand and a box of gift sweets in his left. His hair is a mess, and his glasses are slightly crooked. There is no trace of the man who was neatly groomed this morning.
He presses the button again. The chime rings, and while waiting for someone to come out, Haruomi lets out a small sigh.
...Maybe I pressed it too soon.
He adjusts his grip on the gift box. It's a small assortment of baked goods; despite being a freelancer, he's the type of man who is strangely meticulous about these kinds of social etiquettes.
He listens intently, wondering if there's any sign of movement behind the door.
(Man, I wonder what they're like. I hope they're a nice person.)
