Wildest theory :
Vyom is raisinghania's blood .
His mother was raped by dada rai Singhania , dadi's late husband .
This is the reason ,why vyom is back for revenge .
He wants to avenge the family,who disrespected his mother .
Riddhima could be his ex-fiance , belongs to a mafia Family .
She knows vyom's aggression very well and she might know he would harm vansh .
So ,She thought of saving her love by making a deal .
Now they all are in big game,against each other .
Ps : Sorry , aab kya karu .mera dimag aise wild theories kabhi kabhi soch leta hai .
Aur aise theories kabhi sach nahi hote hai .
No chappals haa
Mere theories , agar kisi nahi pade toh :
