The Four-Person Doomsday Survival Squad

(Apocalypse + zombies + one female lead + stockpiling supplies + decisive and ruthless, no saintly do-gooders + underdog makes good + rigidly straightforward man) (No System, no invincibility, no fantasy elements) A novel with none of the usual extras. The apocalypse arrives, the zombie virus spreads, and people turn into zombies one after another. To escape the zombies' attacks, we have no choice but to retreat to the place we know best: our dormitory. Faced with hordes of zombies outside, will you choose to end it all alone, or find a way to struggle for survival in this apocalypse?
