By using ghatiya Anurag probably meant he dint wanted to maligned the Friendship bond/feeling that he have with Prerna .
He still thinks of her as his Friend and tries to seek confirmation from Prerna.
He is gonna friendzone her I guess 😆 , until Prerna makes him realise.
On second thought it could also mean that the thought that whatever Anurag is doing is out of jealousy and HE WANTS Prerna , not because Naveen is married and involved in sex trafficking racket ...
this Soch Anurag found as Ghatiya ...
Anurag is still far away from "mere Dil Prerna pe aaya toh ... ... probably that will come in Mohini or Komolika or Bajaj phase
