Death is from Cold

In 2037, the world plunged into an apocalyptic freeze, an unnatural cold claiming billions. Jiya, a gentle student, awakens inside the seemingly intact Hwaseong High School, a lone bastion of warmth amidst the glacial wasteland. Trapped with a dwindling number of classmates, the school's lights and heaters miraculously persist, yet a terrifying realization dawns: the cold outside isn't their only enemy. An insidious dread festers within the school walls, hinting at a truth far more chilling than the blizzards beyond. Jiya must overcome her inherent pacifism and rally her desperate peers, for survival demands not just warmth, but an understanding of the malevolent force that now hunts them from the shadows, ensuring that death, indeed, is from cold, both inside and out.
