I have a headcanon that Ron took Hermione to the restored Hogwarts Library (that had been renamed in her honour) and gave her a book called Us: A History that worked like a Pensieve filled with their history so far, and on the first blank page there was the ring.
I may just make a one-shot about that.
Thanks for the submission! That’s a great headcanon! And that sounds like a great idea for a one-shot!
