The bond between Bunny, Naina, Avi (Aditya Roy Kapur), and Aditi (Kalki Koechlin) serves as the emotional backbone of the movie. It portrays how friendships evolve from the reckless abandon of youth during a trekking trip to Manali to the more complex, bittersweet realities of adulthood at Aditi's wedding. The film reminds us that while people change and move apart, the memories they share remain like a "box of sweets"—always safe and ready to be revisited. A Cultural Milestone
The film follows the lives of four friends: the restless and ambitious Kabir "Bunny" Thapar (Ranbir Kapoor), the introverted and studious Naina Talwar (Deepika Padukone), the impulsive Aditi (Kalki Koechlin), and the loyal but directionless Avi (Aditya Roy Kapur). The story is split into two distinct halves—the first capturing a life-changing trekking trip to Manali, and the second reuniting the group years later for Aditi’s lavish destination wedding in Udaipur.
