In Diya Aur Baati Hum, after long battle of struggling with emotions, Sooraj (Anas Rashid) decides to bring his love Sandhya (Deepika Singh) back home. Though he loved her, due to an issue where Sandhya preferred duty over family made him throw her out of the house.
Bhabho had been trying a lot to bring Sandhya back home but in
vain. Babasa, who was also upset with Sandhya, got to know her
value and wanted her back with Sooraj. He tried to convince Sooraj
and also had given money to go to Scotland and get her back home,
but Sooraj ignored.
It was after Bhabho got admitted for kidney transmittion, and his brothers ditched their family, Sooraj felt Sandhya's absence. Sooraj's brother Vikram and Mohit, and their wives Meenakshi and Emily had taken Bhabho's thumb impression on property papers when she was asleep.
During Republic day celebration, where Sandhya was getting bravery awards, instead of Ankur, Sooraj takes the award. He gives a heart touching speech, where he praises Sandhya and accepts his mistakes. He calls her back home. Listening to this, Sandhya comes back home and welcomed by family.
While Meenakshi is happy that Sandhya is back and Bhabho would forgive them. The situation would turn worse as Bhabho doesn't forgive them for their mistakes. Meenakshi asks Sandhya if she didn't go to Scotland? The same question is echoed by Bhabho and Bhabasa. Sandhya lies saying she didn't clear the exam, and so she had to stay back but Meena again argues. Babasa warns not to ask any questions and says Sandhya is their second Sooraj.
Bhabho asks Sandhya to wear sari for pooja, but shocked to see her in salwar kameez. Sandhya requests if she could wear salwar kamez at home always. Rathi family is stunned to see Sandhya like this. Bhabho asks the reason why she wants to wear salwar kameez when she used to wear sari always.
Does Bhabho doubt Sandhya is hiding something? Seems like Sandhya was the lady who donated kidney to Bhabho and to hide the marks she wants to wear salwar kameez!
