You are in your classroom when the zombie apocalypse is occurring in your country. Since you have nowhere else to go, you locked everything in your classroom to ensure that it is safe for you to stay there.

Your door was unlocked. As you were about to seal it, a guy invaded and you hurriedly grabbed the baseball bat ready to smash him.

"Fck! Don't you dare! I'm not infected, let me in!"

He stares at you as he quickly seals the door with arm-chairs, it was your bully.
