Another possibility is that they would take a stroll in the moonlight around their new home. They would hold hands and reminisce about their adventures at Hogwarts. Harry might tell Ginny how much he loves her all over again, and Ginny would respond with sweet kisses, and then they would go back inside to have a warm drink and cuddle by the fireplace.
In some fanfictions, the wedding might be in danger. Maybe Voldemort's remaining followers try to disrupt it. This would lead to an exciting showdown where Harry, Ginny, and their friends have to use their magic skills to protect the wedding. It could also be a chance for Harry to show how far he has come since the end of the war, using his leadership and power to keep everyone safe while still enjoying his big day.
Maybe they go to a wizarding cottage in the countryside. They explore the nearby magical forests together, discover new magical creatures, and Ginny could teach Harry some new Quidditch tricks in the large open fields around the cottage. And of course, they have cozy evenings inside, cooking together and snuggling up by the fireplace.
Some fanfictions might depict them going on a little adventure right after the wedding. Maybe they use magic to go to a special place they've always wanted to visit together. There, they would have a picnic under the stars and talk about all the things they plan to do in their married life, like starting a family and traveling the wizarding world.
In some fanfictions, they could have a dance. Harry would be a bit clumsy at first, but Hermione would guide him. They'd laugh and twirl around the room. After that, they might sit on the balcony, looking at the moon and talking about their hopes for the future, like having a family one day or making the wizarding world an even better place.
One possible scenario could be them renovating their home at the Burrow. They might be adding new rooms for their future family. Ginny could be using her magic to make the place more cozy while Harry helps with the physical labor, like moving furniture with a levitation charm.
One romantic scenario could be a ceremony in the Forbidden Forest. The trees are magically lit with twinkling lights, and the centaurs are there as silent witnesses. Ginny walks down an aisle made of wildflowers, and Harry has a look of pure love on his face as he sees her.
They might get married and start a family right away. In fanfiction, it's common to see them settling down and having kids, living a peaceful life after all the chaos of the battle.
One possible scenario could be that they have a peaceful family life. They might raise their children in the wizarding world, teaching them about magic and the values of love and courage. Harry could be involved in the Ministry of Magic, perhaps working on improving the safety and equality in the wizarding community. Ginny, on the other hand, might continue her career as a Quidditch player or become a Quidditch coach, passing on her skills and passion for the sport.
Well, perhaps they might have a moment where they look through their old Hogwarts photos together. It would be really endearing as they laugh at the memories and realize how far they've come. Also, they could have a special meal that they both prepared together, enjoying each other's company and savoring the food while chatting about their future.
Perhaps they would start the night with a slow dance in their chambers. The soft music playing in the background as they look into each other's eyes, feeling the deep love they have for one another. After that, they might sit by the fireplace and talk about their hopes and dreams for their future together, like having a family or building a more prosperous kingdom.
