A spirit girl falls in love with a human boy who dies saving her, then spends the movie trying to undo it by breaking every rule of the spirit world. The animation moves like watercolor, fluid, gorgeous, sometimes frustratingly soft on narrative clarity. What hits is the raw transaction of it: she trades her own world, her future, her safety, all for one person she knew for three days. The film doesn't judge her for it. It just shows you the cost, frame by frame, and lets you decide if love that reckless is beautiful or destructive. By the end, you're not sure which one you believe, and that uncertainty is the whole point.
A spirit realm exists beyond human perception, where supernatural beings orchestrate the natural world: emotions, seasons, storms, the passage of time itself. Chun, a young spirit girl, transforms into a dolphin to finally witness the human world she's only read about. Her curiosity becomes dangerous when a violent storm traps her in a fishing net. A kind human boy saves her, but drowns in the effort, leaving Chun devastated and guilty. Back in her world, she discovers the boy's soul has been reincarnated as a tiny fish, lost in an endless ocean of transformed human souls. Determined to find him and make things right, Chun begins a desperate journey that will test everything she believes about sacrifice, love, and what it truly means to save someone. This story moves between two worlds separated by more than distance, exploring how actions ripple across the boundary between the living and the ethereal. What Chun discovers about herself along the way challenges her spirit realm's ancient rules.
