I certainly feel

I certainly feel that..yashsam r involved in this plan either directly or indirectly..

I honestly see no reason for Yash/Sam to turn negative esp Sam.. Yash was Roshni's one time lover so maybe he could cause some harm to SidNi's relationship to get Roshni back but I doubt Sam's involved. 🤔 I think they are trying to mislead the viewers with those suspicious scenes of Yash/Sam.
But I could also be wrong. For now, let's just enjoy those precious SidNi moments.

Yash is really gud & inno till now... I have no doubt on him. But this sam may do something to separate SidNI but she s not such a clever to do such plans and all as u say😛
