Virat is a confused soul. Even before he got married to sai, his whole relationship with pakhi is kinda ridiculous. In 2 days, he fell in love. And now he claims that they are "best friends". If they really loved each other, why didnt they open their mouth! Also now that paakhi is married to samrat, what is the point of pining after her and promising to still never give his heart away to someone else....that means he is saying he will still continue to harbor feeling of love for his brothers wife!! So that's still not ok. And as the "mature" guy does he really think that a marriage can actually remain strictly a contract....how is it fair to ask someone to get married to you, live with you and your family, share your life and room for 4 or 5 years (duration of medical course) and then still tell his legally wedded wife "to not have any other expectations from him". What does that even mean?!
Sai did not want to marry him but eventually the poor girl was pressurized into giving in. He has thrown her into this family circus where everyone hates her and obviously she will react. How does he expect her to stay uninvolved after he "married" her and brought her home!
Ever since she has got married to him its just been drama, she has only one thing that shes nervously looking forward to which is her results and getting into college. And even though she has maushi, ashwini and shivani who are usually supportive none of them understand her dreams and aspirations like virat. She literally only has him to share her thoughts with. And hes so bipolar with her. One day hes mad, one day hes supportive, then hes mad again!
No matter what sai said to pakhi, it was TRUE and the decision to react on that and leave was pakhi's. He keeps talking about being mature....so if pakhi is mature she shouldn't storm out because the immature sai said something to her right!
