Make some use of Gauri

I believe that the character can be used to some benefit to the story. When Purvi cried her heart out to Gauri, she revealed her 'sacrifices' for Ovi's happiness.

Now, if and when Ovi starts crying about betrayal (and there was a certain amount, I don't deny that. But not so much that Ovi can portray herself as a fairy princess of purity and truthfulness). When and if this happens, Gauri, who is satunchly Purvi's friend, can open up and tell the whole family Purvi's standpoint, and perhaps remind Ovi of her own underhand deals.

At least then, the families can consider Purvi's view with that of Ovi's.
