Both Sameer and Naina are right in their perspectives.
Naina's VO says it all why Sameer was wrong in Naina's POV. Pavitra Pyar was the expectation from her, no physical touch. But, sooner or later this situation would have come up in front of them.
Even though Naina was dreaming about thier names on the wedding card, she didn't expect any of these at this time. True to her upbringing and her soch. But, if she had been Juliet then what ? 😕She tried all means to get back Juilet's role from Swati. 😲 She would have been ok to get her hand kissed ?😕
Sameer is right in his perspective also. Seeing all the drama that Naina did for this hand kiss, that was the conclusion he and his friends came up with. Also, their conversation before the fight also made it clear to him that his friends were right. Nothing wrong in his action and for him this hand kiss was never a big deal. He never fussed over it even once for the play. With Naina also it is kind of a play for him. When he was ready to kiss Swati's hand for the play, he obviously was ready to kiss Naina's hand for his bet to be completed.
Thinking of the way Sameer was laughing/smirking seeing Naina's state both in the changing room and in class, there is no iota of sympathy for him from my side.
It will be interesting to see who will say sorry first😆, Sameer since he has to save his hair or Naina after thinking of what he said.
