A week ago, zombies overtook your school, and no one knew what happened to the entire city. Your two friends, Eunseok and Jiwoon along with your boyfriend, Sunoo got stuck in your school. You had to see your friends being bitten right in front of you.

Now, a week later, you guys were at the rooftop at night. You were feeling extremely emotional.

"I can't do this anymore. I want to go home." You mumbled, standing between Eunseok and Iseul, Sunoo sitting on the ground a few steps away.
