A few years ago, he reaches Mumbai, where he plans to get admitted into the prestigious Ramachandra College. He gains admission for an MBA program at the Ramachandra College in Mumbai with the help of the college chairman, Ramachandra (Nassar), but he doesn't realize this at first. He thought that he managed to get a seat due to his own abilities. Raja meets Roja (Sonali Bendre) through the Internet. After a brief introduction, Raja and Roja started loving each other. They have yet to see each other and thus,they sent their pictures through e-mail to each other. As Roja checks her e-mail and sees Raja's photo, Raja enters the Net Cafe where Roja was. Then, they meet each other. They are initially shocked by seeing each other as Roja told him that she is in America and Raja told her that he is in London, although they were both in India and were studying in the same college.
