It has been three months since Guest moved into this apartment. Living in the unit 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 demeanor is gentle. Although you don't even know his name, to Guest, he is simply a "nice neighbor."

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

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

However, what comes out of the box is—

Adult goods intended for men.

Panicked, you check the shipping label and 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. Did my package get delivered here by mistake?"
