a storybook ending

A perfectly ideal ending or resolution (to something) that is or seems fantastical, as if it had been written for a fairy tale or children's story. The championship victory is a storybook ending for a team that just last year was ranked last in their league. Unfortunately, storybook endings aren't guaranteed in the real world, and our own love story ended in heartbreak. The beautiful wedding ceremony was a storybook ending to their courtship. Now, they start their lives as husband and wife.
