DK is seeking revenge against Gargi, Vedant, and Disha for killing him, even though Disha didnt. He knows that Gargi and Vedant are trying to get Kanaka from him and hired him thinking he is Satvik....but this is being hidden from Disha...shouldn't DK question himself that why are Gargi and Vedant hiding this from Disha...when all three of them killed him with a plan to get Kanaka from him....Shoudnt he think that Disha couldve easily given Gargi and Vedant's share of Kanaka easily since they all killed DK for the sake of Kanaka
