well its very simple....elder sister ka kuch to asar hoga na choti behan par.....the main pronblem of aaraina is her ego...its deeply hurt because of ronak....i can't blame her since ronak is wrong this time....even now her ego and attitute comes her way so she doesn't want to accept she is in love with ronak...she is thinking how can she fall in love with a horse trainer....thats the reason she is denying....
she needs someone to pump her soul out so that she understands that she is deeply and madly in love....i think Prats might do that because only a elder sister can make her realise love since she herself is going through the beautiful feelings....
but both sisters are having one attitute in LOVE and that is STUBBORNESS......they are deeply and madly in love but doesn't want to accept and gives a hell time to Shanky and Ronak
i feel bad for Shanky and Ronak they are throwing themselves in a well for loving this two stubborn sisters....
i think we will need to get ready to see Shanky-Ronak being Devdas
