Where Did I Go Wrong?

Life is a complex thing for someone like Drishti,
It doesn't get easier when her elder sibling is always at odds with her.
She thinks about mending the ties with her, but that's all she does, she thinks .... A lot.
Drishti is a typical good girl of her parents; she scores the best marks, speaks politely though less and never argues.
She is a silent girl, though her head always seems to run on the train, catching the ideas, making them meaningful and then join to finally make sense.
There's a boy she likes, and for the first time, she speaks without giving much thought to her parents about the boy who, in return, set her up in marriage.
Now her sister seems angry, Drishti wonders, why?
She suddenly becomes the victim of her big sis's glares and sharp taunts.
What will happen when, at last, at the age of 19, Drishti made the decision to marry the boy against her sister's wishes?
And what will happen when a storm is waiting for her in the new marriage, and the masks of the people she thought were her own are revealed most painfully?
And what is that secret of her family, for they are trying so hard to hide?
