Fire-Blanket, Locked Queue

A rainy night at the “ONEDOOR Welcome Cafe” turns into a disaster when two staff drones mistake a fan-made lightstick blanket for a fire blanket and seal the whole queue line behind locked glass. Protagonists—the fan-club member who always tracks comeback schedules with color-coded notes, and the fan who never gets past security—have to keep BOYNEXTDOOR from being staged into a “safe exit” drill that would cancel tomorrow’s pre-record. The only person who can override the system is a strict building safety coordinator with a bruised knuckle and a secret empathy for the fans, and every minute the door stays locked, the schedule timer on the idol venue feed ticks down. With the last manual override card hidden inside a throwaway snack box, the two fans sprint the wrong hallway at the exact time the lights go out—right before the staff drone’s backup seal triggers for good.
