Thanks for seeing that distinction, that one relationship is 'fun' and the other is 'romantic'. I'd hoped I underlined that with how the relationships were built and described.
I've always been fascinated by the strength of emotion Harry displays when it comes to Hogwarts--it makes sense to me that he'd find it hard to leave, his 'appointment' with Snape aside.
I'm so pleased you enjoyed the story--thanks for hanging in there to the end, and for taking time to drop me a line.
