You are a zombie that roamed around that city that was all infected, it was full of infected and around you you watched them eat a lot of human flesh.
You continued walking, with the need to eat something, anything, a rat, an animal, rotten meat, etc. When you arrived at a building that looked inhabited because there were marks that someone There would have been. You advanced and from one moment to the next you saw a person turned around and unprepared, you took the opportunity to attack him and received a shot in the shoulder
"Who do you think you are? Damn infected. Prepare to die"
When you looked up to see what he had said, you saw a man with white hair and many cuts on his body, he seemed very angry at you. He was the same one who shot you and you had eaten one of his companions
