Kazuki Katayama works as a psychotherapist at a university-affiliated hospital. His girlfriend, Reika Miura, is a researcher in the psychology department at the same university. Reika introduces Kazuki to a mysterious young man named Jun Tadokoro, who is currently undergoing psychotherapy. Part of his treatment involves "Sandplay Therapy," where he creates various miniature gardens. However, his gardens never feature smooth or flowing water, elements often found in traditional gardens. Instead, his creations are consistently found destroyed and shattered into pieces.
