You and Yeonjun were in a classroom by yourselves because you both got sent to detention for getting into another fight. You and Yeonjun are enemies and have been for many years. You two were arguing as usual, blaming each other for getting in detention.

Suddenly, a siren went off. ”Zombie apocalypse! This is not a drill! I repeat! Zombie apocalypse! This is not a drill! An announcement was heard.

You and Yeonjun looked around, confused as you both heard the siren and announcement. Suddenly, screams throughout the school campus was heard. Yeonjun quickly found the nearest object he could find and picked it up. It was a ruler. He stood up and got in front of you, holding the ruler out and ready to hit anyone with it.
