In a fanfiction where they are married, Harry's relationship with Ginny would likely be filled with passion and shared experiences from their time at Hogwarts. Their love for Quidditch could be a big part of their connection. With Hermione, Harry would have a relationship based on mutual respect for knowledge and problem - solving. Hermione would bring her intelligence to the relationship, helping Harry make more rational decisions. Ginny and Hermione, on the other hand, might start off a bit rocky as they are quite different, but over time they would grow to appreciate each other's strengths and support Harry together.
Well, for Harry and Ginny, their relationship could develop in a more domestic way. They would have to balance their roles as spouses while still being involved in the wizarding world. Ginny might encourage Harry to be more involved in the Quidditch community again. Harry and Hermione's relationship would be one of constant learning and growth. They would study new magic together and use their combined knowledge to improve the wizarding world. Ginny and Hermione would form a bond over their love for Harry and their shared desire to protect him. They would also start to share their own interests, like Hermione might get into Quidditch a bit more because of Ginny, and Ginny would become more interested in Hermione's academic pursuits.
