After watching the episode, where Shaan puts engagement ring on Natasha's finger, one question came to my mind which still lingers on my mind.
Does Shaan really love Khanak?
Before he met Khanak, he was in love with Natasha and was to get married to her. Later he got married to Khanak and spent time with her. So when he was holding Natasha's hand for inserting ring, did he not feel even for a moment that it was not Khanak's hand?
If he could feel her presence by her fragrance, then he should have definitely realised it was not Khanak's hand, the moment Natasha placed it on his hand.
May be I am expecting too much from Shanak.
