Snow Footsteps

The world is frozen with blue snow falling. A teenage boy with a prosthetic leg, Seo Seon Woo, starts walking south to take the dead girl, Choi Yi Seo, home.
A world that has lost and forgotten warmth. A pace that is too slow to keep up with the pace of the world. Limping footsteps, pushing through the thick snow.
Where will those footsteps lead? Who will they meet, what will they experience, and where will they arrive?
Those footsteps, which will soon be covered in snow, are trampled upon.
