The concept is also popular because it allows fans to explore a different side of Hogwarts. With Draco and Hermione as head boy and girl, there are new power dynamics and social situations. It gives writers a lot of room to play with the Hogwarts rules and traditions, and also to develop a romantic relationship between two unlikely characters in a more believable context. For example, they might have to work together on disciplinary matters or school events, which can lead to some really engaging storylines.
