Siddharth never thought a normal school day could change everything. One moment, his best friend Karan was there, laughing, arguing, and making promises that felt unbreakable. The next moment, he was gone. No proper goodbye. No explanation. Just silence... and a single promise left behind. As days turn into questions, a damaged letter becomes the only clue. Determined to find the truth, Siddharth, along with Amrita, begins a journey that takes them beyond classrooms and into unfamiliar cities. But the closer they get, the more complicated things become. Some promises aren't easy to keep. Some friendships don't fade with distance. And some journeys... are only the beginning.
