Sai took this impulsive decision thinking Virat truly loves Shruti and so she can't force him to stay married to her (Sai). This major decision comes as a huge shocker to Virat but as usual, he doesn't want to clear any misunderstanding.
While Virat is not letting Shruti go through any kind of pain and sorrow, even going against his own family and his wife for the sake of her and her new born baby, slowly, Shruti here is geting attached to Virat
All this time, he got caught up in misunderstandings so much that now as a result he is hated by his family and his colleagues. Even Sai hated him at one point.
Pakhi recalls how Virat betrayed her first and then betrayed Sai and now everyone. Samrat can see how shocked Pakhi is so he asks her to control her feelings she is not the only one disappointed.
