WAIT HOLY SHIT WE GOT A SLICE OF LIFE HAPPY ENDING VERSION

There's another ending?

It's a different au done by a different author! It's a collaboration by the two writers with the same characters, just different settings. The zombie world is a video game in the other AU and it's set in a high school theme.
