The zombie apocalypse has been going on, some survivors gradually lost their humanity due to the brutality of the apocalypse, they even killed people and ate them to survive.

You are bitten by a survivor, you managed to escape into a building and sat against the wall with a deep wound, thinking you're going to die, as you nearly lost consciousness, a guy with burgundy hair approached and touched your wound.

"You don't seem very well, let me help you, try to bear the pain a little, okay?"
