The show is about Sagar and Vidya! Vidya is from Benares, and because of her uncle and aunt, she is illiterate, Sagar is mentally challenged, and they both got married..Sagar has three sisters who are his step sisters, and they dislike him! The oldest and evilest step sister is Sindoora, and she is married to Aniket, and they both have a son called Bharat. The second oldest step sister is Mahua and she is married to a flirtatious Karthik. And the youngest step sister is married to guy named Harsh, who used to harass Vidya back in Benares...Vidya's aunt and her daughter now live in Vidya's house (Singh household) Vidya's aunt is Hema, and her daughter is Shaloo...Vidya is quiet and meek and Sindoora uses this to her advantage to taunt her, and uses Vidya's illiteracy against her, to cook up evil plans against her, because if Vidya gets closer to Sagar, the more he gets distanced from her, and she fears he might get better...
I hope that helps!
Keep smiling...
Love
Soni
