In the crowded, neon-lit streets of Mumbai, a hopeful singer Raj Salman Khan chases his big break in the city’s bustling music scene. One fateful day, he rescues a young woman who has fallen in front of a train and stays by her side as she is rushed to the hospital. The woman, Pooja Oberoi Rani Mukerji, the daughter of a wealthy family, survives but slips into a coma. Her father, Bharat Oberoi Rajeev Verma, rushes to the hospital, and the family, seeing Raj there, assumes he is Pooja's husband Romi, a man she eloped with whom they have never met. To spare her father a potential heart attack, Raj fabricates the identity of Romi. Monty Vinay Pathak appears as a loyal friend who offers guidance during this delicate deception.
As the family grows settled with the idea of Romi, Pooja's best friend Jahnvi Preity Zinta begins spending a lot of time with him. The trio forms a complicated bond, with the family treating Raj as a beloved extension of their household. Then Pooja awakens from her coma and, to everyone's astonishment, also falls for Raj. In a candid moment, the two women reveal to Raj that they both love him using signs with a raised hand; Jahnvi realizes Pooja loves Raj and lowers her hand, signaling a bittersweet truth that unsettles the arrangement.
The romantic tangle deepens, and Raj and Jahnvi’s relationship wanes under the strain. On the day Jahnvi is scheduled to be engaged, she unknowingly takes Pooja's cell phone—a mix-up that underscores how closely aligned the two lives have become. Knowing Raj will never marry Pooja if Jahnvi remains in the picture, she decides to step away. Pooja, sensing the stakes, answers a call on the mistaken device, and Raj’s best friend pleads with Jahnvi to break the wedding and return to Raj. A revelation unfolds, and Pooja finally clears the air about Raj and Jahnvi, leading to a reunited pair—Raj and Jahnvi—while Pooja makes a bold choice for her future with Rahul Khanna Shah Rukh Khan.
The film culminates in a delicate balance of forgiveness and new beginnings. Pooja’s path moves toward a future with Rahul, signaling a fresh start for her, while Raj redefines his place within the circle of friends and family. In a brief, light note, Anjali makes a cameo appearance by Sana Saeed Sana Saeed, adding a final touch of charm to the story’s close.
