Sarah considers Charlie responsible for the untimely demise of her younger sister Rosie (Charmila), who once used to be Charlie's love interest.

Charlie moves into the family home to take care of the children, Asha, Vinu and Mariah. Charlie wins over the younger children, even earning the nickname 'Uncle Bun'. However, the 16-year old Asha, who is a typical spoiled teenager, treats Charlie with contempt. While staying with the family, Charlie is often tormented by the memories of the past, when he was in love with Rosie. Asha clashes with Charlie when he sternly forbids her to meet her boyfriend Roy, who apparently had a shady character. At a local club, Charlie runs into Roy, who is revealed to be a serial womanizer. There, Charlie also meets Geetha (Khushbu), a dancer in the club who gets attracted to an affable Charlie.

On their way back, they run into Geetha, who follows Charlie all the way to his house and gets acquainted with the rest of the children as well, much to Asha's chagrin. Charlie manages to interrupt another of Asha's date with Roy. She reaches her home and vents her rage by physically abusing the elderly housekeeper Gloria, (Philomina) who leaves the house in tears, much to the shock of Charlie.

Upon Geetha's persistence, Charlie shares his sordid past with her, which further deepens the bond between the two. Charlie thwarts another date of Asha with Roy at a film theater, leaving her seething. When a child's play goes hilariously awry, Mariah is greeted by the young neighbor, who also liked Charlie. When Charlie goes there to fetch Mariah, Asha sees it as a golden opportunity to turn the tables against him. Asha asks Geetha to go and see things for herself. An otherwise harmless dancing spree frames Charlie in front of Geetha as a flirt. Devastated, Geetha splits up with Charlie.

Roy arranges a private meet up with Asha at an isolated house. Picking up a stray lead, Charlie reaches the place in time, beats up Roy and brings Asha back home. A violent Asha attacks Charlie and accuses Charlie of destroying Rosie's life. It is revealed that while dying in Charlie's arms, Rosie told him that her act to commit suicide was the result of her being cheated on by another man. Charlie silently took the blame all for himself, not wanting to tarnish her name. It is that chain of horrid events, which has made Charlie to save Asha at all costs, while under his watch.

In a fit of frenzy, Asha locks up Charlie while struggling with his asthma, cuts off the power supply, leaving her siblings scared in the dark. She runs away from her house and reaches Roy's.

However, Charlie stops her in the nick of time. On their way back home, Charlie tells Asha all about the past and why he took the blame for the past fourteen years.
