Mansaram gets worried when he comes to know that the priest has gone out for a couple of days. However, he does not give up and decides to meet Pradhan. Meanwhile, Rohan meets Dev and tells him that initially he was not interested in marrying but now he has promised Maheshwari and will keep his word. He then asks Dev about his heartthrob, but Dev tells him that he could not meet her. Meanwhile, Mansaram meets Pradhan and enquires him about the kid who had played the role of Krishna. On the other hand, Shanti warns Radhika of dire consequences if she refuses to marry. Chanda tells Radhika that she has no other choice but to marry the youngest grandson of the Purohit family. Radhika is shocked when Mansaram also agrees with Chanda.
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?
