Yes, it is quite a unique take. In the original series, Harry and Malfoy are more like rivals. But in this fanfiction, it turns the relationship on its head. It might explore different aspects of their characters that were not as prominent in the original, such as hidden admiration or a different kind of dynamic that we didn't expect.
It is unique. The idea of Harry Potter being part of a Malfoy - centered fanfiction means it likely delves into the Malfoy family's world more from Harry's perspective in a way the original books didn't. Maybe it shows how Harry could have been influenced by the Malfoy way of life or how he might view Draco Malfoy in a more positive light, which is a huge departure from the main story.
Definitely a unique take. Fanfictions often play with the existing canon. In this case, the focus on Malfoy within the context of Harry Potter gives a chance to re - imagine the whole wizarding world. It could explore things like how the Hogwarts houses interact differently if Harry has this new relationship with Malfoy. It might also show how the overarching plot against Voldemort could be altered if Harry was more involved with Malfoy - related things, opening up a whole new set of possibilities for the story.
