I have a different theory on aao saheb's behavior
I don't think aao saheb is negative rather i think she is just pretending to be negative just coz she wants anupriya to stand on her own feet n be independent...somewhere deep down aao saheb knows that anupriya is too naive n this is not good for her
See everyone hates anupriya n disrespects her except kalyani...so i think aao saheb is pretending that now she is against anu so that kalyani can help her n may be after that they can form a relationship...n at the end of the day kalyani is aao saheb's grand daughter n she must be thinking ki woh rao house mein hi rahe
So i think this whole hating drama is aao saheb's plan nothing else she is still very much cares about anu
