Kunal's role

We already know Sid is cautious of Kunal. We are also suspecting that after the raaz is out, every1 except Kunal will leave. Also, it is a fact that he will stay back to win Roshni back (which will never happen) . But what I am trying to figure out and wonder about is what tactics he will bring to separate SidNi. I'm thinking that he might stay like RV. The only difference is RV was after money and Kunal is after Roshni.

he is here to stay and will turn negative but have to wait and see what he exactly wants ??this guy is very cunning 😆
