One common theme is the exploration of their deep, passionate love. Since they have a strong connection in the original series, fanfiction often delves deeper into the romantic and physical aspects of that connection.
Another theme is the idea of secrecy and discovery. In some fanfictions, they keep their relationship under wraps at first, and as the story progresses, they gradually reveal their feelings more openly. This adds an element of intrigue. For example, in stories where they start off as friends but secretly have stronger feelings, and then they explore those feelings further.
The theme of growth is also prevalent. Their relationship isn't static in fanfiction. They grow as individuals and as a couple. Ginny might become more confident in her love for Harry, and Harry might learn to fully embrace his feelings for Ginny, all while dealing with the challenges that come with a relationship that has such intense emotions involved.
Love is a very common theme. Most of these fanfictions focus on the deep and abiding love between Harry and Ginny. Another theme is adventure. Since they are from the wizarding world, they often go on adventures together, which are exciting to read about.
One common theme is secrecy. Since their relationship might not be fully accepted in the wizarding world, they often have to keep it a secret. Another theme is the exploration of new feelings. They might be used to their own relationships (Hermione with Ron and Ginny with Harry in the original series), and this is about them exploring something different.
Family is also a big theme. They come from different family backgrounds, and in fanfiction, how they blend their families or start their own is often written about. For example, how Ginny's large family interacts with Harry, who has no real family of his own at first. And there's also the theme of friendship, as they have friends who play important roles in their lives even as they are in a relationship.
One common theme is power. In a dark Harry scenario, his power might be more uncontrolled or misused, and Ginny could be either a stabilizer or a catalyst in that. Another theme is secrecy. They might keep parts of their relationship or Harry's true nature a secret from others.
One common theme is miscommunication. Often, they fight because they haven't fully expressed their feelings or intentions to each other.
Family is also a common theme. Their relationship is not just about the two of them but also about how they fit into the Weasley family and how they will start their own family in the future. Fanfictions might show Harry finally feeling at home with the Weasleys because of Ginny. And the theme of friendship is there too. Their friends like Ron and Hermione play important roles in their relationship and in the stories, either supporting or sometimes causing some small tensions.
Another theme is the idea of self - discovery. Fem Harry may have different insecurities or strengths due to her gender, and the fanfiction often shows her journey of self - discovery while being in a relationship with Ginny. It can also include how Ginny adapts to this new version of Harry.
One common theme is protection. Harry often feels the need to protect Ginny, which can come across as possessive. For example, he'll be extra vigilant when other guys show interest in her. Another theme is loyalty. Both Harry and Ginny are extremely loyal to each other, and this loyalty can be expressed as possessiveness. They see each other as their own and will fight for their relationship.
Another theme is the exploration of their individual powers and how they complement each other. For example, Harry's courage, Ginny's fierce spirit and Susan's intelligence might be combined in different ways to solve problems or face challenges in the fanfictions.
Love and relationship development is also very common. Their relationship deepens as they face the challenges of the Muggle world together. For example, they might have to hide their magical abilities while in public in the Muggle world, which brings them closer.
