Another reason is that it allows fans to delve deeper into the characters of Harry and Ginny. By creating different scenarios of their meetings, writers can show different aspects of their personalities. For example, in some fanfictions, Ginny's boldness is emphasized more when she meets Harry, which adds an exciting dynamic to their relationship.
There's also 'A New Perspective' which takes a different approach. It shows Harry and Ginny's meetings through the eyes of other characters at first. This gives a unique view on how their relationship is perceived by those around them and then dives into their own interactions more deeply.
Well, they might start a family right away. In some fanfictions, they get married quickly and have a bunch of kids. They could also go on adventures together, exploring the wizarding world outside of Hogwarts.
In some fanfictions, they might have an emotional reunion. Harry could finally let go of all the war - related traumas and just focus on his love for Ginny. They may embrace tightly and share a long - awaited kiss, realizing how much they've missed each other during the war.
A great fanfiction in this regard is 'When Potters Meet'. Here, James and Lily are brought back to life briefly and they cross paths with Ginny. The story focuses on Ginny's reaction to meeting the parents of the man she loves. It shows her respect and admiration for them, and there are some really sweet moments where they exchange memories and advice about Harry.
Ginny might support Harry by simply being there for him. In the face of everyone else turning their backs, her presence can be a great comfort. For example, she could sit with him at meals when no one else will.
One possible reason could be miscommunication. Maybe Ginny feels neglected by Harry because he's so caught up in his own heroic deeds and doesn't pay enough attention to her. So she might seek comfort or excitement elsewhere.
There could be many interesting fanfictions on this topic. One idea could be that in this fanfiction, the 'force' might be some sort of magical or emotional force that binds Harry and Ginny even closer during her pregnancy. It could explore how they deal with the impending arrival of their baby while also facing challenges related to this special force.
Ginny might initially be heartbroken. She could retreat into herself, feeling betrayed and confused. In some fanfictions, she may cut off all contact with Harry immediately.
