It all started with one wrong ice-cream, what you didn't understand? Let's go to the flashback ….
On 15th March, 2006, a 5 year old girl went to get her Great Grandmother a cup of Ice-cream but unfortunately she didn't know that the strict old lady is severely allergenic to peanuts which were added in the said Ice-cream . She went out alone for the first time just to get her old bisnonna her favorite cup of Ice-cream which later on became her last cup. Eating the peanut filled ice-cream her Bisnonna passed away and when her family found out the reason behind the old lady's sudden death No one directly blamed her but internally rejoiced by the fact that now the old lady's Billions worth property would be theirs but luck was not in those Satan's favor as the old lady loved the young girl too much for she always wanted a daughter but didn't get any till the birth of the young girl and hence the young girl was the youngest Billionaire in the country but those cruel Satans could not bear it so all at once started to torture her , not physically as the smart old lady kept five bodyguards for her which were as loyal as a person could be , they were the royal 'Angrakshak' of the Singh family who would die for the life of that five year old princess but as we know not all wounds are visible , similarly those Satans wounded her mentally by blaming her for the death of her Bisnonna and at the tender age of five the young girl fell into depression for she loved her bisnonna to the bits and her death was already a traumatic event for her but as we know all Satans have a king and in the little girl's life it was her Father's youngest brother who manipulated everyone to do what they did his name was Durjan whose name's literal meaning was Satan . He fed Aanya a cup of tea mixed with certain chemicals which could have killed her but seems like the old lady was taking care of her from above and her Angrakshaks came to her on time but she still lost her pancreatic power leading her to become type -1 Diabetic patient .
