Pesi,
You are not alone. Whenever I say Manav, I think of Sushant. Though Hiten is said to be a good actor, for me, Manav means Sushant, always.
Hiten and Ankita work well together, but it can never be like Sushant and Ankita, and therefore PR is a completely different show for me, now.It's like it isn't PR at all.
To me, it's as if Ankita is acting in another serial, with some of her PR cast with her! At least I have an idea what it will be like to see Ankita in another serial with someone other than Sushant as the lead.
With Sushant gone, PR has lost it's charm and special place in my heart!
