Perhaps there's a rival who comes between them. This rival could be another trainer who has feelings for either Satoshi or Haruka. The rival could spread false rumors or try to create a wedge between them, causing their relationship to fracture and their hearts to break.
One possible scenario could be that Satoshi and Haruka have a misunderstanding. Maybe Satoshi made a promise to Haruka that he couldn't keep, like promising to always travel with her but then having to leave for an important mission. This could lead to heartbreak as Haruka feels betrayed and Satoshi feels guilty.
Another possibility is that the Pokemon themselves could be the cause, in an unexpected way. For example, if one of Satoshi's Pokemon gets seriously ill and needs to be left in a far - away place for treatment. Satoshi decides to stay with the Pokemon, but Haruka has to continue her journey. This difficult decision could lead to heartbreak for both of them.
One interesting plot could be Satoshi and Haruka teaming up to discover a new and rare Pokemon species. They might face challenges like difficult terrains and other trainers trying to get to the Pokemon first.
Satoshi is often a very liked character as he is the main protagonist in the Pokemon anime and his adventures are well - known. Fans like to see him in different scenarios in fanfiction.

One possible scenario could be that all their Pokémon friends are part of the wedding. Pikachu might be the ring - bearer, with little ribbons on its ears.

Adventure is also a big theme. These two characters are often on quests in fanfictions, whether it's to find a rare Pokemon or to explore a new area.

Also, there could be a situation where a natural disaster has changed the Pokemon's behavior, and they see humans as threats and start attacking them.
