Rohan meets Dev and feigns his apologies. Padma and Daima are very worried and both feel that the tradition of the royal priest will come to an end if Dev publicly announces Radhika as his wife. Later, Dev is surprised to see Radhika behaving normally. Radhika tells Dev that she has prepared the list of organisations which are run and managed by Raj Purohit's trust. She further tells Dev that all theses organisations, which include the orphanage, widow rehabilitation centre, etc., will be shut down. Radhika then takes Dev to their family temple and asks him to offer prayers there for the last time, as after the fall of the royal priest; the temple will also not be functional. Dev, who is all set to close the doors of the temple, is shocked to see people gather around it and joyous at seeing the future royal priest.
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?
