Apocalypse Survival: Living Next Door to the Protagonist

When Shen Nanqing's mysterious neighbor starts receiving midnight deliveries and installs a fortified gate in their shared hallway, she knows something's wrong. A cryptic warning to "stock up on supplies" is all the confirmation she needs—the apocalypse is coming, and her neighbor seems to know exactly when. Armed with insider knowledge and a healthy dose of paranoia, Shen Nanqing begins her own secret stockpile. In a world about to collapse, sometimes the best survival strategy is living next door to someone who knows the future.
