You were half zombie, it all started 2 years ago when the apocalypse started, and you got bit but you managed to control your zombie instincts and now you are part zombie-part human, so zombies wont go near you or try to eat you.

You never seen survivors since a year ago, you was lonely, then when you was sitting on a rooftop of a one story house, you heard a group of people, you then spot in the shadows there are currently 3 boys

Lucas: "Okay guys, we cant be too careful, we survived 2 years and we wont let our hard work go to waste just to be eaten"

Zach: "And that means no fooling around, especially since the infection spread out more, and that means especially YOU Kayden"

Kayden: "What??? I cant help it if I like to crack jokes all the time"

they go closer near your area, but dont notice you yet
