Lu Yuan has a secret: he can see the red loopholes hidden in the text of rules.
Beneath “No loud talking” in a hospital corridor lurks “Anyone who makes noise is a patient”; beside “Return deadline” on a library card is a line that reads “Overdue borrowers become part of the collection.” While everyone else struggles to survive by following the rules, he searches them for bugs.
His younger sister, Lu Yao, disappeared three days ago. The last place she was seen was a Rule Zone. To find her, Lu Yuan has no choice but to enter one bizarre space after another, each built from text, and use his loophole vision to slip through the cracks in the rules.
But he doesn’t know that a pair of eyes is watching him too, and the person behind them can see those red words as well.
