LoLz
Ok so I'd like to start how everyone is bashing Shivya but you go ahead asking not to bash your post. Just wanted to point this out.
As for the opinion...I think Shivya is a fresh look to the character and I think she's playing her character very well. As for the sparks, the characters need to be developed towards chemistry which they are going towards albeit with a speed of snail.
But I also don't know what sort of sparks needs to be flying between these two. I like there chemistry. Arzoo is shown to be a conservative girl with a new sooch, I mean really the girl does wear a tent for clothes 😆 and has her dupatta wrapped around her ALL the time. And Sahir's all brooding and quite and reserved, but I think Shivya does a beautiful job of showing her character's innocence when facing Sahir.
I think there is chemistry. but that's my opinion. 😊
