Ordinary People's Post-Apocalyptic Survival Notes

A post-apocalyptic story—a virus invades, humans turn into zombies, and the story of two heroines surviving in the metropolis. It is described in a realistic way as much as possible. It is not about supernatural powers, cool stories, super-invincible warriors, nor bloody love dramas. I want to describe as much as possible the story of ordinary people surviving in the apocalypse. This is my first creation, so please bear with me.
