The protagonist is reborn and returns to the seven days before the outbreak of the apocalypse. With his wife who was also reborn, in order to avoid his father-in-law and his family who were vengeful in his previous life, he and his parents moved to a residence on the 32nd floor of the suburbs. They frantically hoarded supplies, strengthened defenses and installed surveillance cameras. After the apocalypse came, they watched with cold eyes as their father-in-law and his family fell into dire straits due to selfishness. The protagonist's family carefully survives in the apocalypse, forming an alliance with other survivors to resist the robbers. After holding on for a year and a half, they finally wait for official rescue and a zombie vaccine, and usher in a new life.
