"The snow melts when it meets the sun, and the light exists for the snow."
The moment when the sun blooms is the salvation of love that melts the cold.
She is like a star guiding him through loneliness, and he is like a warm sun illuminating her bleak world, and each becomes the light of hope at the crossroads of each other's lives.
Concept: The warm sun turns into snow, and love embellishes the world.
