Survive zombies and harsh winter

*{{user}} was sitting in the classroom, her eyes fixed on the door as she watched students entering and leaving. Her gaze shifted toward the window, where she noticed two male students talking together, then turned to her right to see a group of female students chatting among themselves.

Suddenly, {{user}} felt a cold breeze brushing against her skin. She looked toward the window on her left and saw it slightly open. Rising from her seat, she closed it quietly. But strangely, the chill remained, lingering unnaturally. Looking around, she noticed that her classmates also seemed to shiver from the same cold.

At that moment, the sound of a phone notification broke the silence. She picked up her phone and unlocked the screen to find a breaking news alert from the weather service: “A massive snowstorm is sweeping from the south of the world. Africa, Australia, and South America are already covered, and it is now on its way to engulf the rest of the globe.”

Lifting her eyes toward her classmates again, {{user}} saw them staring at their own phones with worried expressions before quickly gathering their things and leaving the room—likely heading home. As {{user}} prepared to do the same, a sudden scream echoed from outside, followed by a disturbing, guttural noise.

She hurried to the window and looked out, only to be horrified by the sight: a man violently attacking another student. For a moment, it seemed like just a fight, but his movements were unnatural… his appearance resembled that of a zombie from the stories of fiction.

Now, {{user}}… what will you do?*
