Well, they could be very protective of each other. Hermione, being the intelligent and strong - willed witch she is, might take it upon herself to teach her little brother all she knows about magic. And her little brother could look up to her and be her biggest supporter in Hogwarts, always cheering her on during her academic achievements and adventures.
Love in its various forms is also a common theme. It could be a budding romantic love, or a deep platonic love. Some fanfictions focus on how they start to care for each other in a way that is different from the typical relationships in the Harry Potter books. This could involve small acts of kindness or understanding between them, especially when they are little, which gradually grows into something more significant.
There is also 'Draco and Hermione's Childhood Encounters'. This fanfiction delves into their early years, creating scenarios where they interact in unique ways before the main events of the Harry Potter series. It often plays with the idea of how their different backgrounds could lead to unexpected friendships or rivalries from a young age.

One common theme is redemption. It often shows Draco's journey towards becoming a better person with Hermione's influence. For example, in some fanfictions, Draco realizes the error of his ways in the context of his family's pure - blood ideology because of his interactions with Hermione.
Another theme is the power of friendship. They come from different backgrounds - Hermione being a Muggle - born and Draco from a pure - blood family. But in fanfiction, their friendship can overcome these differences. It's like in 'Hermione and Draco: Against All Odds' where they support each other despite what others in the wizarding world think.
