Arun takes over the reins of this family, and starts talking to his stepmother. Neema gives birth to a baby boy and they name him Abhinandan. Misunderstandings occur between Sujata and Neema, they escalate, fueled by some gossip from neighboring women, leading to arguments between Arun and her. Then one day, Mahendra, Neemas brother sees Arun with another woman, informs Neema, who quickly packs her things and leaves Arun.
