Ravibarnaboss, a police inspector, on the case of the serial murders, tracks Sanjay down to his flat and attacks and makes him unconscious. Inspector Ravi finds two diaries where Sanjay has chronicled the events of 2002 and 2003. The film flashes back to 2002 as the inspector reads the diary. Sanjay Ramaswamy is shown as the owner of the Air Voice mobile telephone company. In the course of his business, Sanjay sends his men to meet Kalpana, a struggling model, about putting up a billboard above her apartment. The owner of Kalpana's advertising firm misinterprets this as a romantic advance, and in view of a possible lucrative Air Voice ad campaign and other benefits, encourages Kalpana to accept the overture. Kalpana thinks of this as an innocent prank that may fetch her better modelling work, and decides to play out the charade as Sanjay's girlfriend. She gives an interview in a magazine citing Sanjay as her lover interest. This irks Sanjay; as soon as Sanjay knows of this matter, he decides to confront Kalpana but falls in love with her on first sight. Thus, he introduces himself as "Manohar". Eventually both of them spend time together and gradually develop a liking towards each other. The diary ends with Sanjay proposing to Kalpana and promising himself that he will reveal himself as Sanjay Ramaswamy if she accepts.
