Maybe, I am not really sure, but maybe this track is to bring another family member to Sai’s side. Of course, I am saying this after reading the spoilers, but it kind of makes sense. Maybe after seeing how bad Sai’s condition is in the house, Mansi bua will take Sai’s side and defend her. After all, she is the eldest of the house, and if we go by blood, she is the one who has the most rights. If not, then wny would they even think about changing the actress. The fact that they did so means that Mansi bua is going to have some role in the coming episodes.
Let's cross our fingers and hope for the best.
