I hate Pia not Roshni. But unfortunately she is not like Jigyasa whom we hate but don't wish that she shouldn't be there in KS. Poor Roshni everybody hates Pia so much that they want her to die & not show up in KS at all. I wouldn't want to be in Roshni's place.
I never liked Pia's character so when I was catching up with old episodes I always skipped the part with Pia in it. Especially when JW fell in love with her. I still can't get to see it even though he wasn't her jiju then.
