suraj wanted to have a wife who was going to serve his bhabho. that does not put him completeley on a maturity level as far as understanding of marriage goes. if one is marrying only for his parents, where will the individual aspirations go ?
if suraj unlke his siblings cannot even think one small thing for himself except his bhabho's needs wishes, then it is not a complete fault for his siblings to behave the way they do now. before a shouting and such a backward, stubborn mother who doesn't let others voice opinions, then it is bound to happen that vikram, chavi and mohit all go out for respite from suppression and tell lies.
sandhya's rejection of suraj should be a good lesson for suraj. an apt rejection of a man who only wanted a "cow" a subservient puppet, "bhabho ko pankha karti hui, reshmi saadi pehne hue". where is he in this dream as a husband and what are his duties for his wife ?
now suraj as he feels drawn to his wife, a thing which he did not account at the time of marriage plans and how it is going to impact the dynamics between him and his mother; and as he realizes that after all his wife is not a mere voice less puppet, but a very much living person, it is high time he develops a spine for himself.
the way he keeps on saying, "bhabho mei paise de deta hoon", it is him who is spoling his sibs by taking away responsibility from them. we just cannot blame bhabho. Seeing things as they are and thinking good for others, even if it means speaking hard is often the need of hour. One cannot be always the "sweet-talker" and trying to make everyone happy.
hope Suraj's love for Sandhya and his understanding of her charcter as one who cannot tolerate injustice and never lying; will slowly make him realize what he was missing within him and how it will not do to bring Sandhya any closer to him. He needs to grow on the maturity level of standing upto morally righteous things and not just helping here and there, that wil lead him to me the true diya for his baati.
I wish all the success to him in this realization and attain Sandhya's love, for it is really a wonderful feeling that in the whole world there is that one person, who was a stranger but now he means everything to her. it is such a richness !
hope the story-writers and the directors of the show keep this sensitive and sublime understanding living in all the episodes as the love story and family dynamics develop as we go ...
