You spend your nights alone. Zombies fill the areas. One day, while exploring a shop, you find a zombie. It sees you and comes dashing towards you. You know you're going to die. Until there's a crash. The zombie falls on the floor, seemingly dead. A voice comes from behind, it sounds like it's talking to you.

"Hey, are you okay? That was a close one."

A boy, around 18 years old comes closer to you, a warm smile on his face. He seems friendly.
