well ya she was unfair when he wanted to play holi wit her and she yelled at him....at tht point i really felt ...she was being rude and mean!
but not at otehr places ....like when she was dancing wit chunnu ...i wont say it unfair as its not real marriage ...and she doesent know his feelings!she was juss doing sum masti ....and playing holi ...and if ranbeer was getting jealous and feeling bad ..definately tht were his feelings!
if u see kanya's point of view ...she actually is not answerable to him for dancing wit sumone else!! so i dun find her fault there egarding being unfair to ranbeer!!
but ya ...she cud play wit him too and shud hav been nice to him ...it was unfair on her part to just avoid him completly as soon as chunnu came!!
well seeing on kanya point of view i agree...well RanKan marriage is contract and as for now though we knows she loves ranbir but she haven't realise it and still rannu is a stranger to her but when chunnu enters he is her childhood best friend and who she can have fun with and shares all her secret and happiness with him
rannu jealousy is his part of feelings because he have madly fallen in love with kanya but kanya feelings is till unknown
but then not playing holi with rannu is really very unfair and mean of kanya as rannu did for her so much of good deeds for her and her family
