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.
The Suga x Daichi Omegaverse caught fanfic probably has a lot of elements that play on the characteristics of the Omegaverse. For example, it could be that Suga is an omega and Daichi is an alpha, and they are caught in a compromising situation. This could lead to all sorts of drama, like dealing with the reactions of their peers or having to face the rules of their Omegaverse society. Without reading it, it's hard to say for sure, but these are common themes in such fanfics.
Well, from what I know about Omegaverse fanfics, the 'caught' aspect in the Suga x Daichi one might be really interesting. In this type of fanfic, the relationship between the characters is often at the center. If Suga and Daichi are in an unorthodox relationship within the Omegaverse, being caught could mean a big change for them. It might force them to reevaluate their relationship, or it could cause external forces to come into play, like family or community reactions. There could also be power dynamics at play if one is an alpha and the other an omega, which would add another layer of complexity to the story.
