I did not wish it to remain platonic. I am happy that they were able to get together.
I read a book called On the Island, by Tracey Garvis-Graves. In this book an older teacher and her student are marooned on an island... for years. I was rooting for a relationship there too.
If the relationship had remained platonic, there would be no intimacy, no jail sentence, no yearning and no book!! (Sorry, I just had to say that).
BTW, I try to avoid reading other's answers until I have written my own. It seems that I am the only person rooting for a relationship? I never had a daughter of my own, but perhaps if I had, I would see things differently.
