Radhika is shocked when Rohan shoots Dev. Rohan is elated to see Dev lying motionless in a pool of blood and assumes that he is dead. However, before Rohan can forcibly take Radhika, Dev strikes a heavy blow on his head. Rohan collapses on the spot, and Dev and Radhika escape from there. Soon Viraat and his men arrive and get shocked to see an injured Rohan. Rohan comes to his senses and resumes his trail for Dev. Dev and Radhika reach to a makeshift medical camp and quickly hide in one of the tents. Viraat, Rohan, along with their men and few policemen, also arrive there soon. However, before they can find Dev, Barkha (Benaf Dadachanji) intervenes and misleads the cops. She tells the cop that she saw Dev and Radhika running towards the forest. Soon, the coast gets cleared and Radhika thanks Barkha. Radhika then introduces Barkha to Dev and tells him that she is her childhood friend. Barkha, who is practicing physiotherapy, gives first aid to Dev and assures Radhika that the wound will heal soon.
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?
