The plot could revolve around an alternate universe. In this universe, they are not superheroes in the same way. Artemis is more of an artist and Kid Flash is just a regular guy with a love for speed. They meet in a more normal setting, like a coffee shop. As they get to know each other over time, their relationship develops and the kiss is a natural progression of their growing feelings.
A common theme is the exploration of their hidden feelings. In the original series, their relationship might be somewhat ambiguous, so fanfiction often dives into how they really feel about each other beneath the surface. Another theme could be the consequences of their relationship becoming public within the team. It adds drama and conflict to the story.
Immediately after the kiss, they might be in shock. But then they could start to act more protective of each other. Their relationship would likely become more intimate, sharing deeper secrets and relying on each other more during missions.
The more perceptive friends like Batman might notice the change in their dynamic right away. He'd probably keep an eye on them to make sure it doesn't interfere with their work as heroes. Others like Aqualad might be a bit surprised at first, but then be happy for them. He'd understand that their relationship could bring out the best in both of them.
One popular place to find such fanfiction is Archive of Our Own (AO3). Just search for 'Kid Flash and Artemis Kiss' on their site, and you'll likely come across many well - written stories. Some might focus on the build - up to the kiss, exploring their relationship dynamics within the context of the Young Justice universe.
In such a fanfiction, the author might focus on the cultural differences between their two characters. Kid Flash is known for his speed and somewhat carefree attitude, while Artemis is more serious and skilled in archery. Their marriage could be a story of two different worlds coming together, and how they learn from each other to make their relationship work.
Teamwork is also a big theme. Since they are both part of the Young Justice team, many fanfictions focus on how their skills complement each other during missions. For example, Kid Flash's speed and Artemis's archery skills can be combined in unique ways to defeat villains. There are also themes related to family and identity, as both characters have their own family issues and aspects of their identity that are explored in fanfiction.
One possible scenario could be during a moment of victory. After a tough battle, as they catch their breath, the adrenaline and shared sense of accomplishment lead to an unexpected moment of closeness. Their eyes meet, and before they know it, they share their first kiss. It's a spontaneous act, born out of the bond that has been growing between them through all their adventures.
