404 Does Not Exist on February 30

"I woke up in an apartment that I could never leave. The calendar on the wall stopped at February 30th, which did not exist. The anchor brooch in my pocket was hot. The blank document in the USB flash drive automatically wrote: 'The whistle at the dock will take away your memory.' When footsteps outside the door sounded for the twelfth time, I finally discovered that the person in the mirror was not me."
