There's a fanfiction I read where Ron and Hermione are getting married and Harry and Ginny are helping with the preparations. It has some really sweet moments like when Harry gives Ron some advice on married life based on his own experiences with Ginny. And there are also some funny parts where Ginny teases Hermione about her wedding jitters.
A really interesting fanfiction idea could be a time - travel one. Ron, Hermione, Harry and Ginny are sent back in time to the Marauders' era. They have to navigate the different time period while also dealing with their relationships. For example, Ron might be a bit jealous of how close Hermione gets to the young Sirius Black, and Harry has to make sure Ginny stays safe in this more dangerous time.
One great fanfiction could be 'The Golden Quartet's Adventures'. It focuses on their friendship and the various challenges they face together in the wizarding world. The characters are well - portrayed, and it has an engaging plot that keeps you hooked from start to finish.
One great fanfiction could be where Harry and Ginny have a magical wedding at Hogwarts. The whole castle is decorated with floating candles and enchanted flowers. Ron and Hermione's wedding might be more low - key but equally charming, held in the Burrow's garden. The four of them could share their joys and also the nervousness of starting a new life together. Their friends from Hogwarts would all be there, like Neville bringing some special plants as wedding gifts.
One possible scenario in such a fanfiction could be that they are on their way to a magical event when the car crash occurs. Maybe they were in a magically enhanced car that malfunctioned. Harry could use his quick thinking and magic skills to try and protect everyone. For example, he might cast a protective spell around the car just before the impact to lessen the damage.
One great fanfiction could be 'The Protectors'. In this story, Harry and Ron use their unique magical skills to shield Hermione from a new dark wizard threat. It shows their loyalty and friendship in a very intense way.
There's a fanfiction titled 'Siblings in the Wizarding World'. This one delves into how the presence of siblings changes the dynamic between Harry, Ron and Hermione. For example, Ron's brotherly protectiveness over his sisters extends to Hermione's new - found sister figure, and Harry's sister has some unique magical abilities that help them in their adventures at Hogwarts. It's a really interesting take on their relationships.
I'm not a big fan of such dark fanfictions, but you could try looking on fanfiction.net. They have a large collection of Harry Potter fanfictions, and you might be able to find one with that plot there.
One common theme is the exploration of post - war life. After the big battle, they have to adjust to normal life again, and fanfictions often show how Ron and Hermione, and Harry and Ginny do this. For example, dealing with the trauma of the war while also building their relationships.
There's a fanfic called 'Hermione's Heroism'. It details how Hermione risks everything to save Ron when he's been poisoned. The author does a wonderful job of showing Hermione's determination and her love for Ron through her actions. It also has a really interesting sub - plot about Hermione exploring some ancient magic to find the cure.
One great fanfiction could be 'The Hand - Held Bond' where Ron and Hermione's hand - holding is not just a physical act but a symbol of their growing emotional connection. It beautifully portrays how their relationship evolves through this simple gesture.
I recall one fanfiction where the 'Mudblood' concept was explored in a very different way. Hermione was trying to find a way to remove the stigma associated with it. Ron was by her side throughout this journey. And Harry's scar was somehow a key to unlocking an old magic that could potentially change the wizarding world's view on blood purity. It was a really interesting take on the characters and these concepts, and it showed how strong Ron and Hermione's relationship could be in the face of such complex issues.
