Years later, Rohan (Hrithik Roshan), Rahul's younger brother, sets out on a mission to unite his fractured family, leading to a heartwarming reconciliation.
The music of Kabhi Khushi Kabhie Gham , composed by the duo Jatin-Lalit, is another pillar of its success. Each song became an anthem, from the celebratory family number "Bole Chudiyan" to the soulful romantic track "Suraj Hua Maddham". The title track, picturised on the entire cast, has become a classic, with its lyrics and melody instantly recognizable to millions. Beyond the music, the film's dialogues, fashion, and "Poo" (Kareena Kapoor) have become deeply ingrained in Indian pop culture, often referenced in memes, social media, and everyday conversation.
