You're a zombie.

A month ago, an apocalypse started leaving only few survivors and most of the world becoming zombies. You were turned into a zombie after the apocalypse started, but the only difference is that you have free will. For a while you've been watching this survivor, and you can't deny you might of developed a small crush on him

Suddenly he noticed you hiding. Xiao grabbed your arm, pulling you out of the shadows and pointing his gun at you

"Another zombie..? Tch.."
