Oh, if you haven't watched it to date, consider yourself lucky. Essentially, this serial was supposed to be about a midget girl Bharti overcoming all the obstacles in her life, starting w/ getting married. But it quickly morphed into a saas-bahu show, very rarely showing her in the context of the obstacles she'd have to overcome due to her height. All the obstacles she did face in her sasural were the usual obstacles these mahaan bahus face in saas-bahu shows.
Anyway, late last year, they did a leap where Bharti's husband died, followed by most of her family, and after the leap, they showed her 2 grown-up sons, and rest of her family survivors. She arranged for the marriage of both her sons to the 2 daughters of one of her employees. The older of them Pari is a total vamp and is married to her younger son, while the younger one Kopal is your usual mahaan bahu type and is married to the stuttering Veehan, the older son.
So now, this serial is just about Pari trying to make her own life cushy and her sister's life miserable. In other words, 2 sisters have turned into a jethani-devrani, w/ the devrani (who's pre-maritally the older sister) trying to make the jethani's life miserable.
If you haven't started watching this, or don't follow it, don't start now. As it is, this serial could end any time if TRPs don't remain high - as it is, it's run for a year & a half.
