3 years later
One day, Jumbo (Satish Kaushik) and Arun go to Nepal, were Jumbo comes across a girl, Manisha (Rambha), who is about to be publicly disgraced. He arranges the girl's freedom by stating that Arun will marry the girl - without conferring with Arun. Arun attends the wedding ceremony, unbeknownst to him that he is in fact the groom and the ceremony is being performed around him, owed essentially to the fact that they were speaking a different language and the ceremony was different from that in India.
Shortly after the ceremony, he discovers that he is now married to Manisha, and had been tricked into doing so by Jumbo. Arun returns to India, where he remains in contact with Manisha, learning that she is pregnant, and learns to speak fluent Hindi from their mutual friend Gopal (Tiku Talsania), whom they met in Nepal. Hiralal now desperately wants a grandchild to lighten up his life, so he requests the couple to adopt a child. However, by this time - Arun now has a child with Manisha in Nepal and proceeds to adopt the child with Kajaal, and they name him Rinku.
Hiralal discovers from Jumbo that Arun has a second wife named Manisha who is in fact Rinku's biological mother. He brings back Manisha from Nepal to India. Kaajal employs Manisha as a house-maid after she helps an injured Rinku. Oneday, after Hiralal and Manisha return from the cinema, Kajaal confronts her father-in-law and questions him why he is favoring the house-maid over his own daughter-in-law. Another day, she sees Manisha feeding Rinku and gets furious. Kajaal tries to marry off Manisha but Arun calls off the marriage. Kajaal attempts to throw Manisha out of the house and accuses either Arun or Hiralal of having an illicit affair with her. Arun slaps Kaajal in an act of domestic violence and then declares that Manisha has as much right to the house as she does, and even more right to be with Rinku than Kaajal - as his second wife and Rinku's biological mother. Jumbo reveals the story of Manisha and Arun's marriage. Hiralal discloses the fact that Kajal is the one who cannot conceive. With Rinku and Jumbo, Arun leaves for his grandmother's village in dismay where he discovers Hiralal and both his wives- Kaajal and Manisha present. The story concludes with everyone accepting the situation of polygyny and living together.
