A disillusioned man, a woman who longs for love but does not dare to love, a second son under the shadow of his genius brother, an elementary school student who has a sudden change in his family, a housewife who lives for her family and even forgets herself ...... A group of desperate ordinary people, at an unexpected moment, peeped into the incredible truth of science: the dark side of the moon that is never shown to the public, the beauty of the moon that is purely objective, and the beauty of the moon that is not shown to the world, and the beauty of the moon that is not shown to the public. The dark side of the moon, the objectively pure snow crystals, the chrysanthemum stone that carries the traces of history, the seabed sediment that engraves the wordless love, the mysterious and familiar extraterrestrial creatures, and the silent but restless volcanoes. ...... Science, created by man to discover the truth of nature, has in turn guided mankind through the mists of everyday life to discover the truth of life. Hearts tipped with worry, loneliness, and agitation discover the path that was already beneath their feet as the stars of science shine.
