At Riverside University, an old red postbox stands under a streetlamp, holding the whispers of students who believe in love, heartbreak, and fate. Every year, during the Retro Fest, students drop anonymous love letters into the postbox, hoping their confessions will reach the right person.
For Rivya Chauhaal, the tradition is childish-until one sarcastic, unintended letter lands her in a secret letter war with Kiaan Virmani, the cold-hearted, popular heartbreaker of the university. What starts as a joke turns into something deeper as their anonymous letters reveal truths neither of them ever spoke aloud.
But university life isn't just about romance. Rivya, the daughter of a strict professor, is constantly targeted by the elite students, mocked for being an outsider in their world of wealth and privilege. When the Midnight Postbox becomes a weapon, used to humiliate and break her, she realizes the game isn't just about love anymore-it's about survival.
Kiaan, torn between loyalty to his old world and the pull of something real with Rivya, is forced to choose. Will he continue being the cold prince of the elite, or will he stand against his own friends to protect the girl whose words have changed him?
As secrets unfold, betrayals surface, and a final letter holds the power to either heal or destroy, Rivya and Kiaan must decide-was it ever just a game, or was their love story always meant to be written in ink?
