A leap of 20 years is shown in this season. Sanam & Seher are the daughters of Zoya & Asad. They are grown up as beautiful girls. While Sanam lives with her grandmother Dilshad, Seher lives separately as nobody is aware of her since she was lost & separated from her family in her childhood. As a result, Seher grows up as a con-woman. Both the sisters are look-alikes but they are completely opposite in nature.
Sanam has lost her past memories due to a severe accident. She couldn't remember even her name. After an incident, she lives in Shaab's house who renames her Jannat. Shaab falls in love with her. After sometimes, Jannat remembers moments spent with Aahil who was her love.
