I think it’s for the future track where Pakhi again plays a mu card with Sai.
As per KD ( Someone correct me if I am wrong) after Virat goes on transfer Pakhi tells Sai that Virat loves her like a sister and a guardian and instigates her 🙄🤦🏻♀️
This happens before the confession. So this zameendaari jaap is important to keep it alive for Sai to misunderstand Virat more and give more importance to vankars favourite Pakhi didi 🤪
