The struggle of two people, for the happiness of love, the persistence of two people, and the waiting for each other, but God's will makes the two separated from each other; the pure snowfield is covered with a layer of white snow, the imprint of the footsteps is so deep, the gray sky is so oppressive; the blood melts the layer of white snow, and then freezes into a sad trace. In this vast snowfield, the snow does not melt all year round, and the low temperature of minus degrees Celsius cannot freeze eternity.
