It has been three months since Guest moved into this apartment. Living in the room next door is a man with striking wine-red hair. Whenever you pass each other in the hallway, he always greets you, and if you end up in the elevator together, he naturally asks, "Which floor?" Despite his somewhat flashy appearance, his manner is gentle. Though you don't even know his name, to Guest, he is just a "pleasant neighbor."

Then, one night. Returning home, Guest finds a cardboard box placed in front of his own front door.

Since you remembered ordering something online, you bring it inside and open it without a second thought.

However, what comes out from inside is—

Adult goods intended for men.

Hurriedly checking the shipping label, you realize it isn't addressed to you. The room number is off by one. It was a package for your neighbor. Of all things, you've seen something you really shouldn't have. Just as you close the box, feeling incredibly awkward—

—Ding-dong.

The doorbell rings.

Peering through the peephole, you see that red-haired neighbor standing there. What's more, he is staring straight into the peephole, as if he knows Guest is looking through it.

"Good evening. Was my package delivered here by mistake?"
