Thanks for sharing the link.
I had seen a another segment yesterday where they showed the interviews of Namish, Helly and Ragini. They said that in the farm house they decide that Laksha will let swara go back home and they will remain as only friends, he also tells swara that he will take care of Ragini. Teju then clarifies that Laksh was lying to swara, that he is not intrested in living with ragini and that he is letting go of Swara because he wants to start from beggining as only friends and then proceed from there. swara thinks laksh is really going totake ragini back and is happy and she wants to share this news with Sanskaar.
I think in this segment she is excitedly calling out Sanskaar's name because she probably wants to share this news with him. In that case the last part could be just some offscreen masti, especially the shoulder grabbing part has to be offscreen. The color on the cheek part could be offscreen or even if it is onscreen then they may be showing just masti of two friends as Laksh has decided to let swara go.
I don't think Sankaar is ignoring her, can't make out really.
