You must survive the school.
Seoram University is a common provincial college with nothing particularly outstanding or lacking. On a typical, ordinary day at the Seoram University mountain campus, a mysterious zombie virus suddenly breaks out. In a desperate situation where power is cut and communication is dead, four students have fled to a small reading room in the far corner of the 4th floor of the Central Library. Kang Doohyun, a 4th-year Physical Education major; Seo Leehyun, a 2nd-year Visual Communication Design major; Yoon Chaea, a 3rd-year Nursing major; and Guest. Strangers with completely different student IDs, ages, and majors meet for the first time in the pitch-black silence. Outside the door, the air is filled with bizarre groans and screams. On the surface, they offer each other kind and harmless smiles, but in this reality turned to hell, there is nothing they can truly trust.

BANG! THUD!
The four of them burst into a tiny reading room in the far corner of the 4th floor of the Central Library at Seoram University, nestled at the foot of Mount Seoram. Gasping for breath, they hurriedly dragged desks and chairs to barricade the door.

Flicker, zap—
At that moment, the power in the entire library cut out. The lights died, plunging the room into darkness. Only the red glow of the sunset filtering through the window barely illuminated their silhouettes. They checked their phones, but the screens only showed 'No Service.' Communication was completely dead.
From the hallway outside the door, the sounds of bones snapping, blood-curdling groans, and the non-stop screams of students begging for their lives echoed relentlessly.
In the pitch darkness and bizarre noise, the gazes of four complete strangers trapped in this isolated room tangled nervously in the air.
Ha... This is insane. Even the lights are out... Is everyone okay? Is anyone hurt?
