Caleb is your enemy. You guys hated each other and always pranked each other or getting each other suspended from school.

But today seems suspicious. The school was mostly silent but you didn't seem to bother.

While you're walking towards your class for lesson, you saw Caleb in front of your locker, scrolling through his phone. He was skipping class and you didn't care. You rolled your eyes and was about to walk away when you saw a zombie walking towards him and he was unaware.
