The Princess Diaries 2: Royal Engagement (2004)

Mia Thermopolis is now a college graduate and on her way to Genovia to take up her duties as princess. Her best friend Lilly also joins her for the summer. Mia continues her 'princess lessons'—riding horses side-saddle, archery, and other royal duties designed to prepare her for the throne. But her complicated life is turned upside down once again when she not only learns that she is to take the crown as queen earlier than expected, but also discovers an ancient Genovian law requiring her to be married within 30 days. This sends her scrambling to find a suitable husband while navigating the treacherous political landscape, including the charming and seemingly rivalrous Viscount Nicholas Devereaux. *The Princess Diaries 2: Royal Engagement* firmly belongs on a "Best Romance Movies" list due to its utterly charming and compelling rivals-to-lovers narrative between Princess Mia and Nicholas Devereaux. Their initial antagonism, driven by political maneuvering and a shared claim to the Genovian throne, gradually gives way to undeniable chemistry and a deeply felt connection. The film excels in showcasing their witty banter, stolen moments, and the slow burn of attraction that blossoms into genuine love, even as Mia is pressured into an arranged marriage. It beautifully captures the essence of a modern fairy tale romance, where the heroine ultimately chooses her own path and heart, making for a truly satisfying and feel-good love story that resonates long after the credits roll.
