What the hell is this dialogue? It's like he is trying to fit in sada shoes in his wife's life. Eww. This man has zero relationship boundaries. Meih tumhara aaba ki kami kabhi poori nahi kar sakta is so different from meih tumhara pati ka kami kabhi poori nahi kar sakta. Today's virat shruti scene is cringe to the maximum. He feels he is doing right thing by betraying his department because vaada is more important to him.
Had vaada is really that much important to him he wouldn't have broke his previous promises just like that.
Pakhi is absolutely right when she said he hides under big words like vaada zimmedari to hide his own intentions and mistakes.
