One possible plotline could be Ginny struggling to fit in at first. She might face prejudice from some Slytherins who assume she doesn't belong. But she could gradually prove herself by using her Gryffindor - like courage in a different way. For example, standing up to bullies within Slytherin house. Another could be her forming unexpected friendships with some Slytherins who are also outsiders in their own way, like those who don't believe in the pure - blood supremacy ideals of some in the house. She could also have a rivalry with some traditional Slytherins who don't want a former Gryffindor in their midst, which could lead to some intense magical duels and competitions.
A great plotline could involve Ginny's relationship with the Slytherin Quidditch team. Since she's a talented Quidditch player, she could bring a new dynamic to the Slytherin team. There could be resistance from some team members at first, but as she helps them win matches, they start to accept her. Also, Ginny might find herself in the middle of a mystery that involves Slytherin's secrets. Her Gryffindor curiosity and Slytherin cunning could help her solve it, and in the process, she could earn the respect of the whole Slytherin house.
A fanfiction in this vein could show Ginny using her Slytherin traits to her advantage in the wizarding world. Maybe she becomes a master at potions, a subject often associated with Slytherin. She could also form unexpected alliances within Slytherin and change the perception of Gryffindors within that house.
She'd probably become more calculating. In Gryffindor, Ginny was bold and brave. In Slytherin, she might learn to use her intelligence in a more strategic way. Her relationships would also change. She might have more complex friendships with Slytherins who have different motives. For example, she could learn to navigate the political intrigue within the Slytherin house.
Well, in some fanfictions, a great plotline is them raising their children. Harry, with his past traumas, and Ginny, with her strong Weasley family values, might have different ideas on how to bring up their kids. For example, Harry might be overly protective at times due to his own experiences, while Ginny wants to encourage their children's independence and exploration of magic.
One possible plotline could be about Ginny adjusting to motherhood while still being an active part of the wizarding world. Maybe she has to balance taking care of the baby with her duties as a Quidditch player. Another idea is that the baby has some special magical abilities that are a mystery to Ginny and her family at first, leading to a journey of discovery.
Well, a plot could be that Ginny is a Slytherin spy within Gryffindor. She's secretly feeding information to Slytherin about Gryffindor's plans in Quidditch or other competitions. But as she does this, she starts to feel conflicted because she really likes her Gryffindor friends.
A great Ginny Weasley hurt fanfiction is 'Ginny in Peril'. Ginny gets hurt in a fight against some dark wizards.

Her friends, especially Hermione and Ron, play a crucial role in her recovery process, which is heartwarming to read.
A great plotline is when they face challenges in their relationship due to outside forces. Maybe some old enemies try to drive a wedge between them, but they overcome it through their love and trust.

Another could be that they face some sort of dark magic threat right after getting engaged which tests their relationship. Maybe they discover a long - lost magical artifact during their engagement that has a connection to their future together.
One great fanfiction could be where they have a magical wedding at Hogwarts. All their friends from different houses come together to celebrate. The ceremony might include spells that create beautiful flower arrangements in mid - air and a Patronus choir. Ginny would look stunning in a traditional white wizarding dress with lace made of unicorn hair, and Harry would be in his best robes.
A third plot could be a story set during a big wizarding festival. Ginny and Bill are both involved in the preparations, but things start to go wrong. They must work together to fix the problems and save the festival. During this time, they might also have to deal with family drama as other Weasleys get involved, and through it all, their bond as siblings - in - law (or just as Weasleys) becomes stronger.
