In Diya Aur Baati Hum, Sooraj (Anas Rashid) apologises to Sandhya (Deepika Singh) in front of everyone. He repents for his mistake of sending Sandhya out of the house and asks for forgiveness. He gives such a heart touching speech, praising Sandhya on Republic day celebration, where she got bravery award that Sooraj's neighbours too wish for their reunion.
At home, Vikram and Mohit speak against Sooraj saying he did a
big mistake by taking family matter to public. They feel that their
family's reputation was at stake by doing so. Meenakshi condemns by
saying that the fact that was kept secret about Sandhya is now in
public which is shameful.
Bhabho stops them by praising Sooraj, saying he did a right thing by accepting his fault in public. Sooraj comes home and hears anklets sound, and thinks Sandhya is back home and asks Bhabho about the same. Bhabho denies and asks him to keep the award that Sandhya got in the room. Sooraj says by accepting his fault, he is feeling good now.
While entering room, he finds Sandhya's dupatta's ghumar on door, he doubt again. He thinks for a while and goes inside and finds Sandhya's photo that he had sent with her. Now he is sure that someone had come home and asks Bhabho. But again Bhabho denies saying none had come home except the milk vendor. She asks him to go to the shop as Birju was waiting for him.
At shop, Birju says that he has got a strange order and is confused. Sooraj asks if it was Sandhya, but Birju says he got the order from a lady who wore Bhurka. Birju gets a box, in which Sooraj finds his scooter keys.
He tries to leave, but the children stop him to help them. There he finds a kite, which has something written on it that only Sandhya could. He finds Bhabho and Chotu conversing about the book that Chotu had left somewhere. Bhabho says Chotu he will find the book where he had left it before.
Sooraj gets hint and goes to park where he met Sandhya last time. He memorises their meet and cries. He is stunned to see Sandhya in front of him. She asks him to take her home for which Sooraj agrees.
It has to be seen if this was dream sequence or real... You never know. If it's real, then we are happy that Sandhya is finally back.
