Since Rajat was Devyani 's first love ( although I doubt,he was her first love.
I am sure she had done some kaand back in Kanpur,like Alka.
But he might not be like Rajeev,so didn't follow her to Delhi)
Anyway,so Devyani always had feelings for Rajat,so agreed to marry him.
And Neel being the biggest Lallu ever, is taking photographs.
But wait!!
Don't put the whole blame on poor Devyani.
Shastriji is to be blamed as well.
He knew that Rajat is the best son in law one can ever have,and Neel is useless.
He thought Rajat might love Anu unconditionally,but he is not Maryada Purushottam,so he will marry someone else in future.
He didn't want Rajat to get out of the Shastri family and get married to someone else,so he got Devyani married to him.
I am sure,if Devyani had not agreed to marry Rajat,Shastri ji would have got Peeya or Alka ( since she is now getting divorced) married to Rajat. 😆
Okk,enough of my bakwas 😆
The moral of the story is that nothing makes sense in the show 😕
And I am not getting it,why was Sumit sooo excited for this stupid leap
Woh toh lallu ka lallu hi reh gaya hain 🤣
