When I was thinking about the scene where Samar tells Manchan that he loves Kaya(๐๐he was so funny in that....the way he says she is so lucky, such a hot and romantic guy loves her๐๐๐), Manchan says something like chote ko bade pasand hai aur bade ko chote(something like that), and I was like I have heard something like that before, and then it struck me that there was a serial of Ekta in malayalam called Kavyanjali(not the Eijaz Khan and Anita one), in that Kavya and Anjali were sisters, and their parents decide to gets them married to this particular family with two brothers. But the kundali of the younger sister(kavya) matches the kundali of the elder brother and the kundali of the elder sister(Anjali) matches that of the younger brother. So Anjali marries the younger brother, while Kavya marries the elder brother. And their mother-in-law doesn't like Anjali, so she starts instigating Kavya against her saying that she might be ur elder sister but here u r the eldest bahu so u have more power than her in this house and all, and she turns Kavya against Anjali.
So I think the same thing will happen here if Samar gets married to Kaya.
This is if ShivGauri doesn't divorce even after Shiv-Ippy affair comes out and the brain tumor is sorted out. I know it is a little far-fetched, but I have a feeling this will happen, since the malayalam was also Ekta's show(Don't know wht happened in the show, have only scene the promos)
