Everything is well. She would absolutely lie to you about this, Prompto, if she felt you didn't need to know the truth. I expect the excitement of so many new people is going to pall soon - it certainly does for me - and then she will need to angry cry and take a nap, but that is a wholly understandable reaction and not too dissimilar to what I have planned for my own afternoon.
