I think someone is trying to frame Palak.. misuse her laptop and cell phone to do something illegal like stealing Noon's new medicine formula and sell it to someone and put the blame it on Palak.. that's how maybe the family becomes against her...no one will trust her except Rithwik and that's when he will go against the family and declare his love and trust and marry her...he will declare his unwavering trust for her .. will go against every one in his family for her..
The theory seems far fetched... but seems a strong enough reason for Rithwik to defy his family and marry Palak..he will not do it for love alone..
The shadow fiddling with her laptop and phone may suggest something like that...
What do you guys think? Any other ideas???
