Also known as "Code No. 404: Those Erased Rules of Survival", there is no heroine. At three o'clock in the morning, a rule in blood suddenly appeared on the glass door of the convenience store.

Delivery boy Lin An discovered that every time a new Rule 404 appeared, someone would be "rejected" from the world. What's even more frightening is that he is the only person who is not affected by memory cleaning.
When the rule that said "Don't give change to customers wearing black masks" became "Cashiers must kneel to customers wearing black masks", he decided to shred this survival manual that was constantly being tampered with.
