People that have a lot in their mind and have a problem of letting their feelings out are the people that become the aim of spilt personality... people that cannot express their feelings, are always scared all the time, and want to be a different person can develop a spirt personality.
well.. as far as I know Kanya isn't like that? well.. yeah she wants to tell everyone about her contract marriage but i don't think that Kanya doesn't let her feelings out😕 sure in front of her parents she can't talk back but for everything else she always stands up for herself! especially in front of Ranbir😆
If Ekta really things Kanya has spilt personality because of these reasons thenn those other people like Vidya from Dulhann, Saloni from Saat Phere, Bani from Kasam Se, Nandani from Kyunki and all those goodyy bahus probably have like 50 billion spilt personalitys walkin around😆
