Kang Minjae (24) works the night shift at a convenience store and barely notices his own life — until translucent "patch notes" start appearing over the world: changelogs of reality, always before they deploy. A delayed bus. A forgotten coin. A spilled cup of ramyeon that corrects itself when he interferes. The notes don't predict. They decide. And one night, a red sealed entry arrives with his name on it: "KANG MINJAE answers a call at 11:47 PM. He must not pick up."
