Rules of the Strange: Night Shift Guards Must Not Swipe a Third Time

My name is Zhang Bao, and I'm a night-shift security guard at a residential complex in the south of the city. On my third day on the job, I found the handover notebook left by my predecessor and learned that the night-shift rules were not to be taken at face value: the extra check mark on the sign-in sheet, the extra person on the security cameras, the card the owner of Unit 301 asked me to swipe for a third time. Anyone who breaks the rules gets "reassigned," and no one ever sees them again. Every rule I write down leads me deeper toward the truth.
