First, decide on her secret identity. Let's say she's a spy for an underground resistance against the Dark Arts. Then, start with a situation where her normal life at Hogwarts is disrupted.

It could be that she is a secret heir to an ancient magical family. In many fanfics, this trope is used to add an extra layer of mystery and power to her character.
When she has a secret identity as a powerful dark wizard's daughter (even if she doesn't follow the dark ways), it creates a lot of tension. Her friends might suspect her at times, and she has to constantly prove her loyalty. This adds a whole new level of drama to the fanfic, like in a story where Harry and Ron start to question her actions because of rumors about her heritage.
Perhaps it's Draco Malfoy in a more complex and redeemed version of himself. He may have come to respect Hermione during their years at Hogwarts, and his secret admiration for her could be a way of showing his growth and change. He might secretly leave her gifts related to her love for books or magic, like a rare edition of a magical text.
In Naruto fanfiction, the jutsus often play a crucial role. When combined with a 'league' - like a group of ninjas - and secret identities, it can create really exciting plots.

Well, in fanfiction about Draco and Hermione's secret relationship, one common theme is the power of redemption.

They might exchange notes in secret, with Hermione helping Draco see the error of his ways in terms of blood - purity ideology. Their relationship is often a slow - burn, starting with hesitant glances and small acts of kindness that gradually develop into a full - fledged, secret love affair that is full of drama and tension as they constantly fear being discovered.
In fanfiction, a Fred and Hermione secret relationship often adds an interesting twist. Writers might explore how their different personalities interact.
