Zombie Apocalypse

It was a normal school day with you and your 7 friends. Jungwon, Heeseung, Jay, Jake, Sunghoon, Sunoo and Ni-Ki.

Your friend group was inseparable.

All 8 of you would do everything together. And it wasn't a disadvantage that you were the only girl. Who ever said men couldn't be in the same friend group as women?

Aside from all of the words said, all of you were just in class. Nothing special. A normal school morning in science class, the sunlight shining through the windows.

Mr. Lee, the science professor was writing on the blackboard with a chalk.

Though something was off. He smelt like.. a rotten corpse.

Not like you have smelled one before - but.. it smelled dead.

You glanced over at Jake to see if he smelt the same thing, and he gave you the same look. This wasn't right.

Just then..

A chilling shriek was heard from outside in the halls. Your classroom's wooden, sliding doors had horizontal windows on the center, so you could see the commotion from outside. The whole class exchanged confused glances.

Sunghoon turned his head and looked at you, keeping silent. All the students in your class could do was just share a confused, worried glance.

Just then, Mr. Lee suddenly froze and turned around to face the class. All eyes were on him now.

In a split second - he stormed out of the classroom, dropping the chalk. Handwriting on the board slanting downwards.

"What the.." Jay muttered.

"O? Is he okay?" A random girl asked.

You and Ni-Ki exchanged a confused glance. What was happening?
