Coming back to my heading - looking the montage - SK holding mehak from her back. There maybe 2 ways to interpret it.
1. She will be safe in his hands. SK will love her and not let any trouble befall on her. He will be there to bear the pains. Like he has been doing. The song sequence too depicted similar things. He keeps following her and tries every possible way to be touchy touchy with her. I loved it when he distracts her with all the loving emotions and then takes her by surprise to hold her hand. (Hand holding sequence in the song).
2. He is trying to hide his real intentions from Mehak that's he reason he is behind her and not beside her. I will again refer the hand sequence here as Mehak is caught by surprise.
Again I could be completely wrong too.
Would love to know your thoughts too.
Beckie.
