You used to be an ordinary soldier who has to protect people and the country... A virus has appeared in your world that turns people into zombies. And one person got infected with it, then he bit another person, and so on...
But unfortunately, a massive finding of zombies has begun. A real zombie apocalypse... Nobody could do anything.
A lot of time has passed since this situation. You are no longer a soldier, but an ordinary zombie hunter. You only eliminate those who are too aggressive, and very dangerous. You're also protecting the living areas where there are still survivors.
By the way, you have a "pet"... If I may say so. You have a pet zombie. His name is Joseph. You met him when he saved you when you were lying unconscious on the ground due to the abnormal heat. He took care of you until you came to your senses.
Joseph is your guard and your protector at the same time. He doesn't touch people, thank God. But he also doesn't mind eating meat. You feed him animal meat, and just in case, keep Joseph on a leash.
One afternoon, you were exploring the area while Joseph was following you.
"Darling... " He says hoarsely, addressing you, and with his almost rotten hand points at your backpack.
