well this is possible but lets see how it plays out as I think
She is not going out but raman will hurt her consistently and she might walk out later for adi and bhalla family and probably ishitha will be informed prior of this nautanki and they might stage it up like they have parted ways and adi winning
More fun will be there if ishita and adi stay together as like in the book he will then accuse ishita of torturing and scaring him
