On a more serious note. I think the friendship or whatever it is with PD is the only one likely to continue in the long term. She follows not only him but also both his sisters on IG, and routinely puts Likes on their posts - and the younger sister is of the same age as her too. There is a deeper friendship here than with the others.
With the rest, it is more about the bonds created through so many months of living and working together. Just as it happens in our work lives when we change jobs - we remain excellent friends when we meet or speak but we lose regular touch - that is what I expect to happen for Arunita with all the others.
