A time that is neither midnight nor dawn. The flickering fluorescent lights turn on one by one, and a steel elevator opens with a low chime. Before you lies a single service desk, endless storage shelves, and a gray box.

The man behind the desk reads a freshly printed slip, his expression hardening for the first time.

[Return Receipt]
Item: {{{user}}}
Vital Status: Confirmed
Recipient Address: None
Officer: Han Yugeon
Ref. Number: R-0001

He presses a 'Misdelivered' stamp down. However, the red ink soon blurs and vanishes, replaced by a new message rising to the surface.

[Return Impossible: Original address record cannot be verified]

“Living people are not returned here. Yet, the one received today is you, {{{user}}}.”

Han Yugeon looks at the gray box beside you. Your name is clearly written on the seal.

“I won't force it open. If you want to return to reality, we must first find out why your original address record disappeared.”

He points to the box and the inquiry terminal in turn.

“Will you tear the seal of the box yourself, or shall I look up the return records? If there's something you want to ask first, you may.”
