Purple Orange Pink Navy Blue Romance Past Goodbye Book Cover Ideas with Love Sky Man Woman Gradient Sunset Silhouettes Sun River Petals Cherry Blossom

A faded, sunset gradient transitions from deep purples and navy blues at the top to soft oranges and pinks at the bottom. Silhouettes of a woman and a man stand on opposite sides of the cover, separated by a narrow, winding river that reflects the colors of the sky. In the center of the cover, where the river narrows into the horizon, there is a subtle outline of a setting sun. Blossoming petals from a cherry blossom tree drift into the air in the foreground, adding a sense of nostalgia and bittersweet beauty.

The title, "Goodbye, One Day," is written in an elegant serif font with soft curves and moderate spacing. The font has a slightly weathered texture to create a sense of time passing. The text is positioned near the upper third of the cover, centered, and in white to contrast with the darker tones of the background.
