As he grows up, he falls for four different girls across four stages of life: Monisha, Nandhini, Geetha, and Sweatha. Each love begins with hope and ends with unsent letters, heartbreak, and a silent promise to do better.Told through emotional incidents, diary-style reflections, and poetic letters he never sends, Letters I Never Sent is a story about how love, luck, ladies, and laziness shape a boy into a man. But when the right woman - Aanya - finally reads between the lines, Joseph discovers that love was never about who stayed or who left.It was always about the one who waited - patiently, quietly, unknowingly.
