The lyrics are about the protagonist knowing that someday the magic will fade away. The moon is sad and the sun is dried up. The protagonist sees their reflection in a puddle and realizes that they are wet from the rain. They wonder what kind of feeling their happiness is. They dreamed of a rainbow melting their tears and the tears were drying at the edge of their cheek. The rainbow appeared in the sky and it rained. The rainbow will eventually disappear but the rain will keep growing the plants. Even if the rainbow disappears someday, they will always look up at the sky. The train shadow runs far in the pure white night. They leave behind silence as they pass. Their heart feels like dancing, wanting to escape. They wonder what kind of feeling this is. Looking away from their face in the mirror is like something from a long time ago. The rainbow appeared in the sky and it rained. The rainbow will eventually disappear but the rain will keep growing the plants. Even if the rainbow disappears someday, they will always look up at the sky. They will never forget looking up at the sky on a rainy day like this. The rainbow appeared in the sky and it rained. The rainbow will eventually disappear but the rain will keep growing the plants. Even if the rainbow disappears someday, they will always look up at the sky. The flowers were blooming in the garden after the rain stopped. They are surely alright. Yes, let's go find an umbrella for the next rainy day. The lyrics are about the protagonist realizing that the magic will fade someday. But even if that happens, they will always look up at the sky and find beauty in the rain that helps the plants grow. The rain is a symbol of growth and hope for the future.
