The creatives must:
bring Bani and Jai together by bringing them together more often to be alone with each other in some ways, etc This will make Bani realise that she does not really hate him but still loves him very dearly. Not only that if she was in love with him than the story should show that she suddenly realises that loving a person means having trust and faith.
make Bani teach Pia a good lesson instead of being afraid of her. Bani must fight Pia back by pretending to be very close to Jai whenever Pia is around. Jealousy of Jai still being in love with her elder sister, might make her yell out the truth abt the ONS.
