So Shweta emotionally blackmails her parents into buying the Pandya family's house for her by pretending to consume poison. She is apparently doing this to take her 'revenge' and for the family to end up on the road.
Not sure how that works exactly. They were being given the money for real. It wasn't some scam. How can they end up penniless if her parents were going to pay them the agreed amount.
Why Shweta even wants their property is another matter altogether. Can't she just stick to her plan to go abroad. Also, why didn't she do all this prior to her marriage. Could have saved herself a lot of trouble.
