All the workers of the mutt are shocked when Barkha and Viraat tell them that an amount of Rs. 50000 is missing from the mutt's safe. Barkha and Viraat, very cunningly, put the blame on Balram. Viraat tells Barkha that they should interrogate Balram, but Radhika intervenes. Radhika confronts Viraat and Barkha, but they remain unmoved and soon Balram is called. Viraat interrogates Balram, but before he can force him to confess, Dev comes to Balram's rescue. Dev asserts that the money which is missing is with him. He tells everyone that Balram had found the money in the pile of old newspapers and had handed them to him. Balram is acquitted, much to Viraat and Barkha's annoyance. Later, Radhika meets Barkha and warns her of dire consequences if she does not mend her ways. Later, Balram thanks Radhika and apologises for underestimating her.
Choti Bahu is the love saga of two soul mates Dev and Radhika.
Radhika, a Brahmin by birth, was adopted and brought up by a family of weavers in a small town called Rawal. Dev, whose family has been in the service of Rajpurohits for generations, visits Rawal as a child on the occasion of Radhashtami. Dev and Radhika meet each other and become good friends. Radhika and Dev's families tie them in the bond of marriage in their tender age.
Maheshwari (played by Pragati Mehra), the eldest bahu of the Purohits, hopes to inherit Dadaji's property. However, her plans hit a snag when Maheshwari realizes that Dadji has willed all his property is in the name of Choti Bahu.
Undeterred, Maheshwari decides to find a docile girl for Rohan (played by Apurva Agnihotri). Maheshwari plans to own the property by controlling and manipulating the Choti Bahu and to this end chooses Radhika for Rohan. Destiny brings Dev and Radhika together after 15 years, when he returns to Rawal after 15 years to find out about Radhika, Rohan's bride.
Will Dev recognize Radhika? Will Radhika marry Dev or Rohan? Will Radhika become the Choti Bahu of Purohit House?
