Well, Ginny could write a song on her guitar about her love for Harry. She plays it for him one evening under the stars at Hogwarts. Harry is deeply moved and it becomes a moment that cements their relationship even more.
Perhaps there's a magical guitar that Harry and Ginny find. It has special powers, like when Ginny plays it, it can calm the most ferocious magical creatures. They go on a journey to figure out the origin of the guitar and along the way, their relationship deepens as they face various challenges together.
Obviously, Harry himself is a central character. Hermione is often included too. She might be the one who encourages Harry to pursue his guitar - playing or be the first one to notice the special connection between his guitar and magic. Ron could also be there, being a bit amazed or sometimes making fun of Harry's newfound passion in a friendly way.
There's also 'The Guitar - A New Magic for Fem Harry'. This one explores how fem Harry's guitar playing is not just a hobby but a new form of magic. She uses it to solve problems and even to fight off dark forces in some cases. It's a very creative take on the character and the idea of using music as a power.
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.
Definitely not. The 'Harry Potter' franchise has a certain set of values and themes. Fanfiction of this sort goes against those values. It's not respectful to the original story, the characters, and the fans who expect a more positive and clean representation of the Potterverse.
