There is nothing wrong in stating facts about his past but I didn’t find it right when she said in the name of friendship you are hiding your love .
what sai said is absolutely true. virat did hide his love behind his friendship. as soon as he got to know that pakhi is marrying samrat, his love converted to best friend. even when pakhi left the house, he said pyaar and corrected to dosti. it is only recently that he has started seeing her as only friend. but how would sai know? pakhi walks into their room as and when she wishes and virat never stopped her. that makes sai think virat gives pakhi right over him. even when sai said that the room is not their’s or his home and family is not hers he never clarified.
she was always made to feel like third wheel between them. but i am glad that this fight happened. virat now knows what sai feels about him and pakhi, so now he can maintain his distance and clarify things to sai.
even sai always reminds him about the deal. she should stop doing that and bringing pakhi into their every conversation. it irritates virat to no end and make him angry. both of them know how to push each others buttons. but i think that is the beauty of their relationship. they can truly only be themselves with each other- raw, vulnerable.
