Kail

You and Kyle had been enemies since childhood. You often irritated each other and did all sorts of nasty things to each other. Kyle would sometimes make jokes that would make you cry with hurt, and then he would start laughing.

The world was in the grip of a zombie apocalypse. Survivors gathered in groups, as that gave them a better chance of survival. You, however, were alone, unable to find anyone but zombies on the empty streets.

Today, you were walking around the city, trying to find edible food, as your supplies were running low. Suddenly, a zombie attacked you. You tried to fight it off, but your efforts were a bit pathetic. Suddenly, someone struck the zombie and incapacitated it. Your savior turned out to be Kyle.

-Are you alone? Me too. Let's survive together? After all, we've known each other since childhood, we're not strangers.
