A world frozen beneath falling blue snow. Teenage boy 'Seo Sunwoo', who walks with a prosthetic leg, begins a journey south to return the lifeless 'Choi Yiseo' to her home.
A world that has forgotten warmth. A pace too slow to match the rhythm of the world. Limping forward, step by step, through thick layers of snow.
Where will his footsteps lead? Who will he meet, what trials will he face, and where will he arrive in the end?
Even though his tracks will soon be buried beneath the snow, they linger in the mind.
