Surviving a zombie apocalypse
On an ordinary spring morning at Zeta High School, third-period classes were proceeding as usual. In the middle of the lesson, unidentified screams and chaotic noises began to drift in from the athletic field. Students looked out the windows, while the homeroom teacher tried to maintain control, telling everyone to stay in their seats. However, the faces of the students looking outside turned pale in an instant. The teacher, too, lost their words the moment they checked outside the window. On the field, people were attacking one another and collapsing, while explosions and sirens echoed continuously from outside the school grounds. As the chaos spread toward the school gates, the campus was instantly cut off from the outside world. Amidst the tension filling the classroom, a single piece of chalk fell from the teacher's hand to the floor. The small sound rang clearly in everyone's ears, like a signal announcing the beginning. At that moment, the entire school fell into extreme chaos, and students began to act for survival based on their own choices. Some try to protect their friends, some search for a way back to their families, and others move solely for their own survival. The day the world collapsed. Zeta High School is no longer a school, but a stage for survival.

Period 3.
The lesson was continuing just like any other day.
The contents of the lecture just written remained on the chalkboard, and only the teacher's voice and the sound of students taking notes echoed quietly in the classroom.
That was when it happened.
The sound of someone shouting urgently drifted in from the athletic field.
At first, I thought it was just a small commotion during PE class.
But soon after, screams and chaotic noises began to be heard in succession.
Students started looking out the windows one by one, and the teacher tried to calm them down, telling everyone to sit.
It's fine, so get away from the windows and focus on the lesson.
But no one moved.
It was because the students' expressions had stiffened in an instant.
Sensing something was wrong, the teacher also slowly turned their gaze outside the window.
On the field, people were running desperately to escape one another, and sirens and loud explosions echoed continuously from outside the school.
The peaceful school was engulfed in chaos in just a few seconds.
A piece of chalk fell from the teacher's hand to the floor.
Tap.
The small but clear sound echoes through the classroom.
In that moment, everyone realized instinctively.
That their ordinary daily life was over.
Someone rushes out of the classroom to get to their family,
Someone heads for the hallway to find a friend,
And someone else locks the door and begins to look for a place to hide.
The school was no longer a space for learning.
It had become the most dangerous place, where only choices for survival remained.
And now.
Your survival begins.
Act calmly, check the window, and assess the situation.
Prioritize friends and lock the classroom door with them.
Act bravely and help the teacher evacuate the students.
