I would recommend 'A Day with Fred Weasley'. This fanfic really captures Fred's mischievous nature well. The reader gets to go on all sorts of adventures with him around Hogwarts, from pranking Snape to exploring the Forbidden Forest in a rather light - hearted and exciting way.
Another option is Wattpad. Some authors post their 'Fred Weasley and Reader Fanfiction' there. It can be a great place to discover new and unique takes on the relationship between Fred and the reader, but it also has a mix of different writing styles and levels of maturity in the stories.
One common theme is adventure. The OC often joins Fred on various adventures, whether it's exploring hidden parts of Hogwarts or going on a quest outside the school. Another theme is love against all odds. Since the OC is not a canon character, there are usually obstacles in their relationship that they have to overcome.
One great Fred Weasley x Harry Potter fanfiction is 'The Unlikely Bond'. It delves into a unique friendship between them that gradually turns into something more. The story is well - written, with great character development for both Fred and Harry. Another good one is 'Fred's Secret'. It focuses on Fred's hidden feelings for Harry and how he struggles to come to terms with them in the midst of the chaos at Hogwarts. And there's also 'A Different Kind of Magic' which shows a magical journey of their relationship that defies the normal expectations in the wizarding world.
A really engaging 'fred weasley fanfiction' is 'Fred's Forbidden Love'. It tells the story of Fred falling in love with a girl from a different house, which is frowned upon in Hogwarts. It delves into the challenges they face and how Fred's determination to be with her is unwavering. The story also has some great descriptions of Hogwarts and the magical world around them.
There's also 'Fred's Unlikely Love'. In this fanfiction, the OC is a shy witch who slowly breaks out of her shell because of Fred. The author does an excellent job of showing their chemistry and the growth of their relationship over time. It's full of humorous situations and touching scenes.
The appeal of Fred Weasley x Harry Potter fanfiction lies in the unique dynamic between the two characters. Fred is a fun - loving and mischievous character, while Harry is more serious and burdened. Their interactions can be really interesting as they balance each other out. It also allows for exploring different relationships within the wizarding world that J.K. Rowling didn't fully explore in the original books.
One great George Weasley x Reader fanfiction is 'The Prankster's Heart'. It beautifully portrays the relationship between George and the reader. Another is 'George's Secret Admirer' which has a really cute plot. 'Redheads and Romance' is also a good one, showing the Weasley charm through George's character.
The plot also matters a great deal. If it's an interesting story that takes Fred on an adventure, like maybe he discovers a new magical creature or has to solve a mystery at Hogwarts, it can be really engaging. And if there's a good relationship development, whether it's a friendship or a romance, that adds depth. For instance, a story about Fred falling in love and how he navigates those new feelings while still being himself is really appealing.
There's 'The Lost Smile'. In this one, George and the reader have a big fight over his dangerous pranks, and it leads to a lot of heartache. Another is 'Broken Bonds' where the reader feels left out when George gets too caught up in his business at Weasley's Wizard Wheezes.
