Like most balaji serials,, anybodys character could be changed.
I think heres how the story track will continue:
After pratz donates her kidney to ariana
Ariana will come out of coma soon.
Then the investigation behind sumo death will continue and then ariana finds out that sumo was lost in her thoughts and thats how her accident happened.
Also , in addition to that she will also find out that shanky and pratz were at there wen d accident happened.
So she starts wondering y prasha was there n especially shanky on his wedding day?
then she has a flashback of aziz telling sumo abt prasha s relationship wen sumo n ariana didnt trust aziz
during that time.
Then she thinksm was that the reason that shanky was wid pratz on his wedding day at accident spot n sumo saw them.
Or she somehow recieves the photos of prasha from pratz ex-fiance.
After that Arian plans to take revenge on prasha.
By marrying Shanky.
But eventually, she tells herself that she has to forget raunak to take revenge on sumo s death.
And slowly she falls for shanky.
But shanky can't forget pratz, his first love.
Pratz tells shanky that their relationship is over coz he is a married man and his love is only ariana.
