On a rainy evening at a crowded railway station, aspiring writer Anya misses her train and accidentally meets Kabir, a warm-hearted stranger. As they wait together, a simple conversation over tea blossoms into an unexpected connection. Kabir reveals that he's been carrying an old love letter he never had the courage to send, a symbol of the chances he let slip away. When it's time to part, he entrusts the unopened letter to Anya, believing every unfinished story deserves another chance. Inspired by their brief but meaningful encounter, Anya writes a novel titled The Letter That Never Reached You. Months later, at her book signing, Kabir reappears. This time, instead of letting fear keep them apart, he confesses that the letter was always meant for the person standing in front of him. The story ends with the two walking away together under a shared umbrella, proving that sometimes the greatest love stories begin with a missed train, a rainy day, and the courage to take a second chance.
