Subway at 1:17 AM

At 1:17 AM, the subway sighed to a stop between Jeongha and Riverside. The map above the doors went dark, then returned with one station name missing.

Phones lit up across the carriage in perfect sync. Every passenger read the same first line: DO NOT TRUST THE LAST ANNOUNCEMENT.

A child pointed at the emergency intercom. The red light was already on, as if someone on the other side had been waiting.

The intercom crackled. 'I can only open one door,' the operator whispered. 'Tell me where your carriage feels warm.'
