This is a very controversial and uncanonical concept for the 'Harry Potter' series. While there might be some fanfiction out there exploring such dark and untrue-to - the - original - story ideas, it goes against the essence of the relationships J.K. Rowling created. I personally don't support such fanfictions as they distort the well - loved characters and their relationships.
Yes, there are likely fanfictions with such a plot. The Harry Potter fandom is vast and diverse, and writers often explore different relationship dynamics. However, this goes against the canonical relationships in the original series.
Fanfiction often involves non - canon and sometimes controversial storylines. However, promoting stories about cheating in a positive way isn't ethical. The Harry Potter series has a strong theme of loyalty and friendship, and such fanfiction goes against the spirit of the original work. So, I don't recommend any of this type.
It's a really bad idea in my opinion. In the 'Harry Potter' books, Harry and Ginny had a strong and loving relationship, and Hermione was their dear friend. To create a fanfiction where Harry cheats on Ginny with Hermione is not only disrespectful to the original story but also to the fans who love these characters for who they are. It's like a desecration of the wonderful world and relationships that J.K. Rowling built.
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.
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.
I think it's a rather disturbing concept. In the Harry Potter universe, the relationships are built on certain foundations. Harry and Hermione are platonic friends, and Harry and Ginny have a genuine romantic relationship. Creating fanfiction based on cheating distorts these relationships and the positive values the series represents.
One common theme could be the exploration of betrayal. Since Draco is cheating, it delves into how Hermione might react to such a betrayal and how Ginny gets involved in this unethical relationship. Another theme might be the disruption of the expected relationships. In the original story, Hermione has her own relationship paths, and this fanfiction concept completely turns that on its head.
There are likely quite a few out there. Fanfiction is a vast world where writers can take creative liberties. But this particular scenario can be controversial among fans who are loyal to the original pairings. It might be interesting to see how the writer develops such an unexpected plot, but it also might not sit well with many who have a strong attachment to Hermione and Draco's individual story arcs.
She could also be very hurt and go into a state of deep sadness. She might isolate herself from Harry and their mutual friends for a while. Ginny would likely question her own self - worth and wonder what she did wrong in the relationship. But as time passes, she might find the strength to move on and focus on her own life, like her career or other relationships.
