I think Vansh IS planning something for Ridz and yes its sort of a trap...but what Anupriya thinks is happening and what Vansh is doing is completely different....that Vansh know what Ridz is doing for whom and what all she didnt do and he know someone from his family is playing games and he is going with the flow pretending like everyone else in house apart from dadi Sia, he too wants to punish her but in truth he is planning on exposing the real face of everyone and that too without harming Ridz...bas dara raha hai thoda...
did u see the sideways look vansh gave AP in the end of their convo? that was a look that says even AP doesnt know the full extent of his plan...
@bold yes yes
He had to give lollipop to mummy ji as she was chewing his brains off
But his plan is much deeper than AP can think of
