What is Atharv's motive behind marrying Kalyani?

To force Malhar to do something like this at the mandap of his wedding? 😆 where lawyers n other people from the court will also be present to witness the situation so that he can prove that Kalyani is more important for Malhar than Pillu, in a result the full custody will be given to Sampada n she will comeback to him.

Or, He just wants to teach both Sampada & Kalyani a lesson, only wants to hurt both of them hence he is marrying Kalyani.

Or, He has some other major hidden motive which i completely failed to guess! What could the that reason? Can any of you guess it?😕

His motive is only to hurt Malhar my guess

a) Malhar's marriage to sampu since he loved her

(b) Sampu again going back to Malhar for her baby

(c) 3rd kalyani's concern for Malhar which he can't disgest even after so much torture Malhar has given her knowing well now that even Malhar has soft corner for kalyani.

my 3 reasons

Even i am also confused , Why atharav is hell bent to marry Kalyani ? He returned the share to Atul.He kidnapped Anu... Why he is so much after this marriage ! He is planning something big .

I think it's the first reason what you mentioned above😆
