Dilip Khanna is Sumesh Agarwal, he was married to Avantika, they had Rishi Agarwal, who is now Angad.
Dilip bought a life insurance policy and faked his death. Rishi got the 15 crore life insurance money. Somesh became Dilip and took Rishi's money. Naina was the caretaker of Rishi. Naina blamed the whole murder scheme on Avantika.
Avantika sentenced in jail for 20 years. Naina from caretaker ban gayi Crore patni.😆
So to cut a long story short, they are all thieves, hopefully Avantika will take revenge from all these lalchees and put them in their place.
