That's just my POV. Firstly I like Sulagna and Angad's pair. They looked really cute in today's episode during the engagement ceremony.
Secondly, Sara will always be Sadhana for me, I don't want her to come back in another role to tarnish Sadhana's character and SaLekh'e memories. If they had to bring her back then what was the point in killing her character and introducing Sakshi opposite Alekh. I know she has an impossible task as she will always be compared with Sadhana but their story is different and unique. Why would I want to see the same SaLekh story again ?
Cool, but all im trying to say is thati feel sahdna and alekh love story had much more potential that what was shown, by bringing back saram they can create that magic again on screen and raise the TRP heheheh. But for some reason i feel sara khan just might come back, and as for angini i feel they are the sweetest and most lovable jodi, they are also creating magic on screen
