Harry might become more at peace. After all the battles and losses, he could focus on the positive aspects of life. Luna, on the other hand, could become more confident in sharing her ideas. She no longer has to be in the shadow of the war and can be more outspoken.
They could become very close friends. After the war, they both have a shared understanding of the trauma and changes they've been through. They might support each other in rebuilding their lives at Hogwarts or in the wizarding world in general.
One possible story could be that after the war, Harry suffers from paraplegia due to some dark magic he endured during the final battle. Ginny stays by his side, being his strength. She helps him through the difficult process of physical therapy. Their love becomes even deeper as they face this new challenge together.
Harry could become an Auror, as he's always been good at fighting dark forces. Ginny, on the other hand, might continue her career in Quidditch. They would support each other's choices. Harry would cheer for Ginny at her matches, and Ginny would be proud of Harry for his work in keeping the wizarding world safe.
He might become very self - reliant. Since he has no one to depend on, he learns to take care of himself in every aspect, like finding his own place to live and getting food. He could also start to study magic more independently, exploring areas that were previously forbidden or not well - known.
For Harry, his growth could be shown through how he becomes more open - minded. He starts to embrace Luna's quirks and her different way of seeing things, which in turn makes him more accepting in general. For example, he might initially be a bit hesitant about Luna's belief in some of the more out - there magical creatures, but as they date, he starts to see the beauty in her imagination.
Some fanfictions might depict them as having a more adventurous post - war life. They could be involved in rebuilding the wizarding world in a more hands - on way. Harry might use his fame and Ginny her popularity among the younger wizards to bring about positive changes. Their relationship would be based on mutual respect and a shared goal of making the wizarding world a better place.
In a lot of fanfiction, they are indeed considered soul mates. Harry has been through so much trauma and Luna, with her off - beat charm and deep understanding, can reach parts of Harry that others might not. For example, she can see thestrals because she has also witnessed death, which gives them a special connection that some writers like to explore as a soul - mate - like bond.
There probably is. The Harry Potter fandom is vast and diverse. Writers might explore this relationship in fanfictions for various reasons. Maybe they want to give Luna a closer connection to the main story through Harry, or perhaps they just like the idea of changing the family dynamics in the wizarding world. Check the major fanfic platforms and use relevant tags to look for it.
Well, when Harry defends Luna in fanfiction, it could be a way to explore different aspects of the Hogwarts' social structure. Maybe Luna is being targeted because of her unique beliefs or appearance. Harry, being the hero - type character, steps in. It not only showcases his character but also gives Luna a chance to shine more. It can lead to interesting plot developments like Luna teaching Harry something in return for his defense.
