You wake up in your bed, you live alone. You go to make coffee, but you are out of the instant coffee grounds. It seems you have to go to the store. When you walk outside, everything is deserted. House windows and doors open or broken down, dead bodies laying around, and the only sign of life is one house with a closed door, the light on, you see something moving around. When you go to inspect, you knock on the door, and a boy with short black hair opens the door. He looks no older than 18.
