Some characters in the harem might be developed as admirers of McGonagall's strict yet fair teaching style. They could be shown as constantly trying to impress her with their magical skills, like a young wizard who practices transfiguration just to get her attention.
One great fanfiction could be 'A Bond Beyond Hogwarts'. It explores the unique relationship between Harry and Minerva in a post - war Hogwarts setting, with Harry seeking Minerva's guidance on becoming a better wizard and leader.
Another theme is wisdom. Since McGonagall is a very wise character, many fanfictions explore how she imparts her wisdom to others, especially Harry. They might have her giving advice on dealing with Voldemort or handling the pressures of being a young wizard in a dangerous time.
One common theme is her role as a mentor. In many fanfics, she is guiding students through difficult situations, much like she does in the original books.
It could be a fellow Hogwarts professor. Maybe Flitwick, as they've worked together for a long time and have a mutual respect for each other. Their relationship could have developed secretly over the years.
One interesting plotline could be McGonagall mentoring a young and troubled student. It would show her nurturing side, which we don't always see in the original books. Another could be her taking on a special mission during the war, like protecting a secret magical artifact. This would highlight her bravery and loyalty to the wizarding world.
One common theme is mentorship. Minerva often acts as a mentor to Harry, guiding him through his studies and the challenges he faces at Hogwarts. For example, in many fanfictions, she helps him with advanced magic classes.
Well, of course, Harry Potter and Minerva McGonagall themselves are often very well - written. Writers can really explore different sides of their personalities. For example, we might see a more vulnerable side of Harry as he confides in Minerva about his fears for the future. And Minerva can be shown with a softer side, perhaps when she's mentoring Harry on more than just academics.
Another plotline might involve a time - travel scenario where Harry Potter and Minerva McGonagall have to work together to change an event in the past that is threatening the future of the wizarding world. This could lead to some really cool interactions as they navigate through different eras.

Another is 'McGonagall's Secret Struggle' which shows her dealing with an old wound that resurfaces and affects her teaching abilities.
