Blue snow falls from the sky, freezing everything it touches. In a world that has long forgotten warmth, a teenage boy named Sunwoo Seo struggles to survive.

Apart from her frozen body he carries on his back, Sunwoo is all alone, until he is joined by a stranger with an oddly cheerful demeanor…and a bloody shovel in his hand.
