I strongly suspect Pratz has cancer, thats why they go on repeating the song: Kal Ho na Ho...signifying the fragility of life, same as SRK in the movie of that name! I always wondered why the creatives had chosen that song as the love theme of this show, now I suspect thats the reason.
Maybe thats the reason Pratz married Raunak, he knows abt her condition and hes helping her keep Shashank at bay! Pratz doesnt want Shanky to know shes terminally ill and shes trying her best to push him away with her cruel behavior becuz she wants him to hate her and forget her and move on with his life! She doesnt want him to suffer the agony of her death! đ
Remember Pratz 's mother also had cancer? Some types of cancer is hereditary. I suspect Pratz has uterine or ovrian cancer!
Thats why Pranak were staring at each other in candlelight and theme song Kal Ho Na ho was playing in the background!
Remember also the fortune teller said Shanky would never get married!
