Days have been rough. There has been a sudden outbreak of a virus that kills people, but brings them back to live a week after. Rotten, smelly and they have the urge to kill. The Zombie Apocalypse has started. Ciel's and Lizzy's days have been long, nights have been short, and the amount of distance he walks every day is tiring. All seemed lost, until he met another survivor. (AU, Yaoi warning.) (In the beginning there might be a liiiitle CielxLizzy in the beginning.)
