There could be some really interesting fanfiction ideas around this combination. The Weasley family is known for their unique and often humorous take on magic. Maybe in such a fanfic, Arthur Weasley could be passing on some old family wisdom about a lemon - like it has some special property in magic that Rose Weasley discovers. It could be a story of discovery and family bonds, with the lemon as an unexpected element that ties the plot together. But again, it would take some digging to find such a specific fanfic.
One possible plot could be that Rose Weasley is doing some experimental magic in the Weasley family home. Arthur Weasley, being the curious and experienced wizard he is, comes across a strange lemon - like object that Rose has. It turns out this 'lemon' is actually a magical artifact from another time. They then embark on a journey to figure out its origins and how to use it safely.
You can try some well - known fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions, and you can search specifically for Arthur Weasley - related stories with the 'lemon' tag. Just be sure to check the ratings and tags carefully to find the ones that suit your taste.
There's also 'Arthur's Forbidden Love'. In this fanfiction, the lemon aspect is more subtly woven into the story. It focuses on Arthur Weasley's unexpected feelings for a character from a different magical community. It shows how he struggles with his emotions while still being true to his family values.
As lemon fanfiction is not something we should promote, in normal Arthur Weasley fanfictions, a theme could be his work at the Ministry of Magic. How he tries to balance his job with his family life. Also, his relationship with his wife, Molly Weasley. How they support each other, and their joint efforts in raising their children, which are all positive and family - oriented themes.
Since lemon fanfiction goes against the ethical and family - friendly nature of the original Harry Potter series, I would suggest looking for general Ginny and Arthur Weasley fanfictions that focus on their relationship in a more positive and clean way. For example, some might explore Arthur's fatherly relationship with Ginny in a heartwarming manner.
In non - lemon fanfiction, their relationship is often one of a father - daughter. Arthur is shown as a loving and protective father. He is proud of Ginny's skills, like her Quidditch abilities and her bravery. Ginny, on the other hand, respects Arthur and looks up to him. She may learn from him about the history of magic or how to fix things around the Burrow.
One challenge is getting their personalities right. Arthur is very curious about Muggle things and has a warm, fatherly nature. Ginny is strong - willed and brave. It can be difficult to make sure these traits are consistent throughout the story. Another challenge is creating a believable relationship dynamic between them. Since they are father and daughter, it has to be a relationship that feels true to the original series.
I'm not really into that kind of pairing in fanfictions. However, you can try looking on some well - known fanfiction platforms like FanFiction.net or Archive of Our Own. Search for the tags 'Arthur Weasley' and 'Lily Evans' and then skim through the results to find ones that might interest you.
I'm not really into lemon fanfictions as they often involve inappropriate content. However, if you're looking for regular Harry Potter fanfictions about Arthur Weasley, you could check out fanfiction.net. There are many great stories there that focus on his character development, his relationship with his family, and his work at the Ministry of Magic.
