RnB don't want II to be involved in the family mess.He wan't her innocense to be intact.Just like preserving a baby.The only people he trust around her was sam,tan and may be Ranjan.
But everyone is trying to get RnB using her.RnB never gave any one a chance.He stayed in Paris whole time.
He came back to India after Sam almost begging.
He was suposed to go back after Lasya.
But he gave himself to his biggest weakness.II
Now he came back to India may be for few days but came back with almost no buisness only for II.
Lucky II is not trying much to get involved with chachu and chachi family.
RnB being only son of Ranajn is causing a big problem.
first he is hating Ranjan .but whether he deserves it or not is still unknown.But everyone deserves forgiveness when they are repenting their mistakes.
Then he is not ready to be part of excelior.So Ranjan will be forced to go to Chachu's family to continue it.
But as Nisha mentioned in a chapter about failures of their family.
In less than an year or two they had ability to bring down excellior to sands.
I believe if RnB even wishes to buy Chachu's shares.His approach would be different and would have completed his work in a week or couple.
I guess RnB is more comfortable will II being in Sam's than hi in his absence
