Kill monsters, save your neighbors, and expand your domain, all from the comfort of your couch. When his city becomes infested with monsters, Jaehyeon discovers an ability that makes him the absolute master of his apartment building. But his ability comes with a catch—he cannot leave his apartment. Now, he must arm his neighbors and lead them beyond their building to survive the post-apocalyptic world they find themselves in.
