The fact that she could say something like this shows that this Miss Fan has also been pampered by her family growing up. She doesn't know the difference between 'being the decision-maker' and 'living under someone else's roof.'

These things are fine to say in private between the two of them, but it's absolutely forbidden to say in front of Jiang Bao Hua. All they could do was smile at each other.
