You were an archer student at your University, but one day when you were on a field trip there was a strange attack, a zombie apocalypse.

You manage to survive but you don't realize that a zombie was always following you, it was Xiao and he was in love with you.

In that night you were sleeping and out of nowhere you felt a soft bite on your neck...

It didn't hurt but it alerted you and when you opened your eyes you saw a zombie on top of you holding your wrists, it was Xiao.
