Later, while praying, everyone is surprised when it suddenly starts raining heavily. Dev, Radhika and Barkha take refuge in a nearby guesthouse. Barkha again gets frustrated when Dev checks in with Radhika and asks her to stay in another room.

Barkha tells Dev that few men had barged in the room and were looking for him. One of them had attacked her when she had tried to catch them. Dev gets worried, but Radhika does not buy Barkha's story. On the contrary, she shocks Dev by revealing Barkha's truth. Radhika tells Dev that Barkha is trying her best to come closer to him. However, Radhika is stunned when Dev chides her and tells her that he is obliged to Barkha for everything. He makes it clear that he will not hear anything against Barkha. Radhika feels helpless, while Barkha feels relieved. Later, Padma is shocked to see Barkha's bandaged wrist. When the Purohit family comes to know about the alleged attack, they feel that Maheshwari is behind it. Padma decides to call the police, but Barkha gets tense and tells Padma that they should not involve police in their family matters.
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?
