Based on the first novel, Spring Snow, of Mishima Yukio's Sea of Fertility tetralogy, it follows the troubled and illicit affair between two youngsters amongst the aristocracy and rich of early twentieth century Japan.

The story traces a father’s quiet confrontation with loss, a computational physicist who has always believed the universe can be measured, predicted, and controlled—alongside his son, a boy who finds meaning at the piano, guided by freedom, feeling, and the beauty of impermanence.Through two opposing ways of seeing the world, science and art, precision and intuition. they move along parallel paths shaped by grief, resistance, and understanding.
