Friendship is a very common theme. Given their relationship in the volleyball context, many fanfictions explore how their strong friendship impacts the team and their individual growth.
I'm not sure specifically as there could be many different fanfics with this pairing. It might be about an unexpected moment where Suga and Daichi are 'caught' in a certain situation, perhaps a moment of surprise, or a situation that reveals something about their relationship within the context of the story created by the fanfic writer.
I've read one where Suga and Daichi have an adventure outside of the volleyball world. They go on a camping trip and face some challenges together. It really shows their bond in a different context. You might find similar ones by searching for 'suga x daichi adventure fanfiction'.
I haven't actually read this specific fanfic, but in general, an Omegaverse fic often involves unique world - building elements such as alpha, beta, and omega dynamics. If it's a 'caught' scenario, it might involve some sort of discovery or revelation between Suga and Daichi. It could be about their relationship being found out in a world where such relationships might be stigmatized or something unique to the Omegaverse setting.
Sure. You can try searching on fanfiction websites like Archive of Our Own. There are likely many well - written daichi x suga fanfictions there. Just use the search bar and type in 'daichi x suga' to find relevant stories.
Fanfiction.net is another option. There are a lot of user - submitted stories there. However, the interface might be a bit more dated compared to AO3. But still, you're likely to find some interesting daichi x sugawara fanfictions if you dig around a bit. Just be aware that the quality can vary more widely on this site.
One great daichi x sugawara fanfiction is 'A Bond Beyond the Court'. It beautifully explores their relationship in a post - volleyball career setting. The author does an amazing job of showing their deep connection and how they support each other in new challenges outside of the sport.
