Well, clearly Kari and TK are the main characters since it's about them being married. But other important characters could be their Digimon partners. For example, Gatomon might be there to offer Kari advice on married life, and Patamon could be TK's sidekick, getting into all sorts of fun and sometimes troublesome situations.
Their friends from the Digimon adventure series would also likely be part of the story. Characters like Davis, Yolei, and Cody might make appearances. Davis could be a bit jealous at first but then come around to support Kari and TK. Yolei might be excited to help Kari with wedding - related things in the fanfiction, and Cody could offer TK some words of wisdom.
One common theme could be the adjustment to married life. How they deal with daily routines, finances, and family together.
TK could be developed by showing his growth into a more responsible and protective partner. Since he was always a bit of a brave character, he could now use that bravery to safeguard Kari and their future. For Kari, her character can develop in terms of becoming more confident in her decisions, especially when it comes to their relationship and the challenges they face together. For example, she might be the one to come up with a clever plan to defeat an enemy in the Digital World.
One possible plot could be Kari and TK navigating through their new married life while also dealing with the challenges of their Digimon partners still being a part of their world. Maybe they have to balance their personal time together with the responsibilities of helping their Digimon in battles or other situations.

Maybe tk would choose his brother as the best man. They've shared a lot of experiences growing up, and his brother would be really supportive. For Kari, her best friend from childhood could be the maid of honor. This friend has been there for all of Kari's important moments and would be honored to stand by her side on her wedding day.
Their wedding could be a small and intimate affair. Maybe it takes place on a beach, with the sound of waves in the background.

The ceremony could be filled with personal vows that they've written for each other, expressing their deep love and commitment.
One plot idea could be that TK and Kari start a new life together in the Digital World. They could face challenges like new threats to the Digital World and have to use their combined skills and the power of their bond to save it. Maybe they discover a new type of Digimon that is causing chaos and have to figure out how to tame it. Another idea is that they get married in the human world and have to balance their digital adventures with their normal lives, like dealing with family reactions and school or work commitments.
Well, fanfiction often takes creative liberties. For TK and Kari to kiss, it could be in a situation where they are in a parallel digital world, away from their usual group. They might be on a quest together and find themselves in a beautiful, yet dangerous place. The stress and the unique environment could lead to a moment of closeness, and then the kiss. It could also be a turning point in the fanfiction's plot, leading to new challenges or a deeper exploration of their relationship.
One common theme could be friendship. If they are characters who know each other well, fanfiction might explore the depth of their friendship, how they support each other through tough times. Another theme could be adventure. Maybe they go on quests together, facing various challenges along the way.
Maybe they love it because it satisfies their creativity. Fanfiction is a form of creative writing that builds on existing works. Kari and Tk could be drawn to the idea of seeing how other fans' imaginations expand on the stories they already love. It can also be an escape, a way to delve deeper into a fictional world that they are already passionate about, and forget about the real - world for a while.
