Hi guys...
I think kamya is Shabd's Step sister and Sareen's step daughter. And he's the one who may have killed either Kamya's mom or Rajveer. And may be he's the one who caused the fire in which half of Kamya's face got burnt. B'cos Kamya knows evreything Sareen doesn't want anyone to get closer to her. So that his dirty secret will remain a secret.
what u think friends....your comments r most welcome... Take care😊
