You've added a new dimension to this.. it's a bit difficult to predict at the moment but the scene was different from both versions. In the Bengali version, she stacks pillows when he caresses her forehead and the Tamil version has this scene of her hand around him accidentally but unlike the Hindi version where Virat just removed the hand, Tamil mein he holds her hand and watches her intently.
Peeking part is also a mix.. but given Sai's Hindi character being the most rigid of the three versions, I don't think she will fall for him first. In fact, I do feel that Virat has already moved towards falling first and not Sai as much.
But it will be interesting to watch who is able to acknowledge the feeling first. I don't think Sai will ever let go of her guard (it may slip accidentally at times) and accept that she's fallen in love, until Virat tells her her that his vaada is no longer between them. Not just tell but repeat a zillion times like he did to let her know that there is one.
