I don't know why but I feel like there will be a huge changes to the story line about Manju Aunty. You all noticed right that we haven't seen Manju Aunty's daughter yet so I am guessing, her daughter probably died due to some illness.
Deep down I just feel everytime I see Manju Aunty in the show that she is faking the smile. After watching today's episode where she did an awesome acting after finding out that Suhana got brain tumor, I am positive that her daughter died because of a Cancer.
