Wandering and escaping all the way, crossing the endless frozen wasteland. There is no end to the snow, and there is no return date on the road. Under this deep snow that buries everything, Only the unfrozen heart in my chest, It is still beating strongly, becoming the last immortal ember in this dead world.
