Soon, they are approached by a Naxalite group to compose songs against the government.They do it for the money and are eventually arrested under POTA.Harini, who is deeply hurt at this revelation, leaves Munna and returns to her parents, despite his insistence that they did not meet before the encounter and that he did not have sex with Rani.As Rani is the only one who can prove that Munna did not have sex with her, the friends begin searching for her.After a few unsuccessful attempts, they are finally signed by Sony Music and record their first album.While celebrating their success, a drunk Krishna accidentally tells Harini about their earlier encounter with Rani.Munna (Siddharth), Babu Kalyanam alias Bob Galy (Bharath), Krishna (Thaman), Kumar (Manikandan) and Juju (Nakul) are five friends.They come from different backgrounds – Munna from a middle-class family, Bob Galy from a Telugu-speaking family, Juju from an academically-inclined family, Krishna from a rich family and Kumar from a poor family.
The gang's album soon releases and becomes a huge hit.
After that, if they are still in love, the parents will not stand in their way.
Although the kids agree to this, they continue to long for each other.
But without Harini, the lead female vocal, the record labels are unwilling to sign them.
When the boys request Harini’s presence for a live show on MTV, her parents accept, but on the condition that Munna sign the divorce papers.
