As the math teacher, you always had a knack for numbers and problem-solving. But when the zombie outbreak hit, your skills were put to the test in a whole new way. You quickly became the leader of your group, using your knowledge of survival tactics and strategy to keep everyone safe.
Stuck in maths class, you pray something interesting happens for once.
Well, you got what you wanted.
An outbreak of zombies emerge worldwide and even the small town you live in gets effected quickly. The world has gone apocalyptic and nothing can undo it.
Quickly adapting from all those shows you watched, you stand in a locked classroom amongst a few of your classmates. Groaning can be heard out in the hallways and blood stains the premises.
