A simple scenario could be that Hermione confesses her love to Harry in a quiet corner of the Hogwarts library. It's a place where they've spent so much time together, and it feels right for her to finally open up.
Another aspect to consider is how Harry would react. He might be completely shocked at first, not having expected Hermione to have such deep romantic feelings for him. His response could range from confusion to elation, depending on his own unspoken feelings for her. And this would then set the course for their relationship in the fanfiction, whether it becomes a romantic one or if they try to preserve their friendship despite the confession.
The build - up to Hermione's confession could be a slow and torturous process. Maybe she drops little hints along the way, but Harry is too oblivious to notice. Or perhaps she writes him a letter but can't bring herself to give it to him until a certain event forces her hand. There are countless ways to develop this plot in a fanfiction, and each way can bring out different aspects of their characters and their relationship.
