The rain falls on everyone equally, but the river only belongs to those downstream who understand what they're asking for. This isn't a story about possession or ownership. It's a song that proves you don't need narrative structure or character arcs to make something true.
A one-episode music piece built around a single song that follows water on its journey. Rain falls from the sky and gathers until it becomes rivers. Those rivers sustain living things as they run onward, and the song keeps following them as they broaden and finally empty out into the vast sea.
