When you must abide by the rules to survive, but find that the rules themselves are full of contradictions - will you choose to follow them blindly, or find loopholes?
Strange rules have come to the world, and every daily scene may become a fatal copy.
Lin Mo, a librarian with mild obsessive-compulsive disorder, accidentally got involved in the "Midnight Rule of Closing the Ancient Books Room" because of his replacement colleague's night shift.
"Rules may be contradictory, but logic is always self-consistent; obsession may be paranoid, but regrets deserve to be heard."
——Lin Mo, on the title page of the duty log in the ancient books room
