Current: Soon Anjali 's wedding will be broken coz of Khushi
Next I think after Arnav comes to know the truth, they will reveal both their pasts..
Prediction about their past:
I have a feeling that, next it will be Khushi's turn to have hatred towards Arnav. Coz it looked like she loved her parents so much,like any child would. But I think that Arnav or one of the Raizada's might be the reason for her parents death.
reasons:
according to the very first promo: Kash mein tumse mohabbat kar pata aur Kash mein aapse nafrat kar paathi
Its like : when arnav was supposed to confess his love for khushi, it didn't happen
later It might be like: when Khushi wants to confess her love for him after everything gets sorted out between them, than I think she will learn about her past and will separate from him or that pervert Shyam might plan something like trying to kill someone in the gupta family. And Arnav might become the victim
