Catastrophe | Haikyuu Zombie AU

In this story, the term "Zombie" nor the concept of the dead somewhat coming back to life eating and infecting other humans is not known in this AU, meaning no one knows what a zombie is so they are completely clueless, but they will be called zombies in the narration, I think this is a First Person Story too. You are in the story as well, addressed as F/N L/N. Now, I know not much people make stories of Haikyuu anymore but I wanted to make one so, here I am, I like zombie stories of series I like for some reason, it's probably about when a character dies or when they are in danger it truly expresses and tests about how much each character cares for another.
