Perhaps in a post - war scenario, Hermione is working on some important magical research and Minerva is helping her. As they spend more time together, they realize their feelings for each other. The plot could involve them secretly getting married and then dealing with the reactions of their friends like Harry, Ron and the other Hogwarts faculty. They could also be involved in some magical mystery that is related to their relationship and the future of Hogwarts.
One plot idea could be that Hermione, after graduating from Hogwarts, returns as a teacher. She and Minerva start to work closely together and gradually fall in love. They face some initial opposition from the wizarding community due to their age difference and the unconventional nature of their relationship, but they overcome it and get married in a small, private ceremony at Hogwarts.
One plot idea could be a story set in an alternate universe where Minerva and Albus got married in their youth. They could face challenges from the wizarding society that disapproves of their union due to their positions at Hogwarts. For example, some might think it would create a conflict of interest. Another idea is a time - travel fanfic where they get married in a different era and have to adapt to the different cultural and magical norms of that time.
One possible plot could be them dealing with the aftermath of their marriage in the wizarding world. There might be some opposition as they come from different houses and have different friend groups. They would have to work through how to combine their lives, like where to live and how to handle their careers, whether it's Hermione's pursuit of knowledge or Cedric's role in the wizarding community.
It could also be about a student's future. Hermione sees great potential in a particular student and wants Minerva to give the student special treatment or opportunities. Minerva, believing in fairness and equality for all students, opposes this. This sets off a battle of wills as Hermione is determined to help the student reach their full potential and Minerva is steadfast in her principles.
A possible plot is that Hermione gets into some serious trouble at Hogwarts, perhaps framed for a major rule violation. Minerva, as a mother - figure, believes in Hermione's innocence and works tirelessly to clear her name. Along the way, they share heart - to - heart conversations about Hermione's past, her Muggle - born status, and how Minerva overcame her own difficulties as a young witch. This deepens their relationship and forms a beautiful mother - daughter dynamic.
One idea could be Minerva discovers Hermione is her long - lost daughter through a magical revelation. For example, a spell gone wrong reveals their true relation. Another could be Hermione facing a difficult situation at Hogwarts and Minerva, as her mother, steps in to protect her in ways a normal teacher wouldn't. Maybe Hermione is being wrongly accused of something and Minerva uses her influence and motherly love to clear her name.
Maybe in the fanfiction, the marriage law is a ploy by a dark wizard to disrupt the order in Hogwarts. Hermione and Minerva have to pretend to be happily married to fool the enemy. During this time, they learn about each other's insecurities and strengths. Hermione might introduce Minerva to some modern Muggle concepts that could be useful in their fight against the dark forces, and their relationship gradually turns into a real and deep connection.
How about a story where Hermione discovers a hidden talent for transfiguration that even McGonagall is surprised by. They then work together to perfect this new form of transfiguration, but face opposition from some of the more traditional - minded professors. Or, in a post - war Hogwarts, they collaborate to reform the curriculum to include more practical and modern magic, all while dealing with the after - effects of the war on the students and the school.
One idea could be that in a world where werewolves are more accepted, Hermione discovers Minerva was once bitten and becomes determined to help her during the full moon. She could research new spells to ease the transformation pain.
In this type of fanfiction, usually Minerva McGonagall discovers Hermione's situation of being abused. She takes Hermione under her wing. Hermione might then start to heal and grow in a more positive environment. Minerva could offer her protection, guidance, and a mother - like figure that Hermione might be lacking. This often leads to Hermione becoming more confident and showing more of her true potential at Hogwarts, away from the abuse.
One plot idea could be that she tries to keep her pregnancy a secret at first, fearing it might affect her position at Hogwarts. But as her condition becomes more obvious, she has to face the reactions of the students and staff.
