Yeah Swara could be his childhood crush from school time...She has always been a smart, intelligent girl who can be the crush of any school boy...
I am not trying to put down Ragini's character but I feel Sanskaar does not care much about Ragini... Closing the door on her face & telling her rudely to go away proved that...
He was affected by the thought of Ragini not coming to his house daily as she is the connection between his family and her family, and not Swara...
If Ragini stops coming to Maheshwari house, then the connection with her family will be lost...
Maybe I am being too judgemental but he seemed to be shocked & insecure of Lakshya-Swara closeness but was cool & smirking for the proposal of Lakshya-Ragini wedding...
Slapping Lakshya on his confession for loving Swara gives an impression that he could be an obsessive person with a sinister agenda...
Why pushing emotionally others for Lakshya-Ragini wedding after learning about Lakshya's love for Swara... He could have done the same for his wedding with Ragini if he wants Ragini to stay with him... Whether others agree for it or not, that is a different point...
