However twisted it sounds her original motive is love. She loved someone, however crooked that person was and seems to have an agenda to become Mukhiyani to revoke one judgement which changed her life.
It was refreshing to see that for the change it is not regular money.
It was not also that my son should become the hair of Mukhi's wealth. She thinks Mukhi took away her love and happiness and is trying to not let him get any happiness.
Was this why Mukhi and Saanvi never united (due to Raami's interfering) and resulted in Saanvi's marriage to someone else and Arjan hating Mukhi for hurting his sister?
Not sure but it seems a chain reaction was started with Mukhi's one decision at that time.
