Given that we know that Anika and Shivaay love each other and there is so much respect between Anika and Om and shivaay and Om the whole idea sounds ridiculous and preposterous.
But given that this is a soap situation badalte der nahi lag time. So why or what could possibly lead to such a scenario?
I am still thinking - revenge track. Anika finds out about obros being the cause of her family's destruction post shivaay love confession. So she marries or forces om to marry her to break up the family etc.,
Maybe something scandalous - like shivika confess, they get carried away in passion, she gets pregnant but shivaay either Is forced to marry Tia or is believed to be dead and to protect her om marries her!! This sounds ridiculous even as I am writing it!!!
Chameli mat Utaana shivik shippers!
