One friends reunion story could be that a group of high school friends who hadn't seen each other for years reunited at their old school. They walked around the campus, reminiscing about the good old days like the time they won the school football championship together. They then went to their favorite diner near the school and shared laughs over burgers and fries, just like they used to.
Well, perhaps there's a mystery at the school reunion. An old teacher who was always a bit of an enigma left behind a strange object. At the reunion, a group of former students decides to solve the mystery. They discover that the teacher had a secret exotica - related past, like being part of a secret society that explored ancient and exotic cultures. As they dig deeper, they find themselves on an adventure full of surprises.
In the fanfiction, Hermione's Muggle friends could be brought into the wizarding world during the reunion. They could meet some of Hermione's wizard friends like Harry and Ron. There could be a lot of cultural clashes and interesting conversations as the Muggle friends learn about wizards and vice versa. For example, they might be shocked to learn about Quidditch and how it's played in the air.
Perhaps in the fanfiction, the Avengers reunite for a more personal reason. One of their own, say Tony Stark (even if he's no longer alive in the main timeline), has somehow sent a distress signal from an alternate reality. They come together, not just to rescue him but also to explore this new and strange reality where things are different. They might meet alternate versions of themselves and have to team up with these versions to solve a problem that is affecting both realities.
A friends reunion story can be heartwarming when long - lost friends find each other again. For example, two friends who had a big fight years ago and lost contact. When they reunite, they forgive each other instantly and realize how much they missed each other. Their hugs and smiles can make the story really heartwarming.
At a class reunion, there could be a story of an old feud between two classmates that was finally resolved. They had been at odds during school for some silly reason. But at the reunion, they sat down, talked it out, and realized how childish they were back then. It led to a great friendship and they even planned to collaborate on a project in the future.
It could be a very emotional reunion. Thor might be initially angry at Loki for all his past misdeeds but then quickly soften as he realizes how much he has missed his brother. Loki, on the other hand, might be a bit guarded at first, still not fully trusting Thor's reaction. But eventually, they would embrace and start to rebuild their relationship.
Well, in the fanfiction, their reunion could lead to them teaming up. Maybe they decide to take on a powerful enemy together. They'd combine their skills, with Ace's fire powers and Sabo's fighting abilities, and create a formidable force. They'd also probably have some deep conversations about their past and how much they missed each other.
Well, in a fanfiction, their reunion could be in a completely new region. Ash has been invited to a special Pokémon event there and Serena, having heard about it, travels all the way just to see him again. When they reunite, Serena has become an even more confident and skilled Pokémon coordinator. Ash is so proud of her growth, and they decide to team up for a new adventure in this unfamiliar region.
They might have a very emotional moment. Sasuke could finally open up about his long journey and all the things he has been through. Sakura, on the other hand, would be so happy to see him again and might just break down in tears. They could share a long hug, a hug that they both have been waiting for for so long.
In a Draco and Hermione reunion fanfiction, they might initially be hesitant. Draco could be ashamed of his past actions during the wizarding war. Hermione, on the other hand, might be curious yet guarded. Maybe they meet in Diagon Alley by chance. Draco could be there to buy some rare potions ingredients for his new business venture. Hermione is browsing the new books at Flourish and Blotts. Their eyes meet, and there's a moment of shock. Draco, trying to be polite, nods. Hermione, after a brief hesitation, nods back. And that could be the start of a series of unexpected interactions.
