Radhika is shocked with grief and finds it hard to believe that Raj Purohit is no more. Barkha too grieves the demise of Raj Purohit and feels that Rohan should also get a chance to attend the funeral of his grandfather. She phones her farmhouse and informs Rohan about Dev and Radhika's marriage as well as Raj Purohit's death. Padma and Daima are very worried for Dev and feel that Dev should break down. Both try their best, but fail. However, Radhika manages to make him cry. Everyone in the Purohit family is mourning, but Maheshwari and Viraat are elated as they feel that they will get hold of the entire property. Later, Rohan arrives and Padma is pleased to see him. Rohan tells Padma that he has realised his mistake and apologises to her. He also meets Dev and asks him to forgive him. Soon, Mathadhish arrives and with a heavy heart announces that Dev's coronation as the royal priest will take place the next day after the funeral of Raj Purohit.
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?
