Nune Baphin Balgeoreum

In a world where blue snow freezes everything it touches, humanity has long forgotten what warmth feels like. Seonu, a teenage boy with a prosthetic leg, carries the lifeless body of Iseo through the snow-covered wasteland, determined to bring her home one final time. The snow will soon erase his footsteps but not the promise that keeps him moving.
