What could be the plot in a 'Harry finds Ginny cheating' fanfic?

Harry could also go into a state of shock and disbelief. He loves Ginny deeply, and to find out she's cheating would shatter his world. He might start to question everything about their relationship, like all the memories they've shared together. And he could become very withdrawn, not wanting to talk to anyone, even his closest friends like Ron and Hermione. He would need time to process his emotions and figure out what to do next.

One possible plot could be that Harry is under the influence of a dark spell. In this state, he kidnaps Ginny because the spell is making him act against his true nature. Ginny, being the strong - willed character she is, tries to break through to Harry and reverse the spell's effect on him.

Maybe Harry is sent on a mission by Dumbledore. Dumbledore has received some strange prophecies that seem to be related to Atlantis.

It could involve a lot of exploration of the Atlantean culture and magic system, which would be really fascinating.

Well, it could be that Harry has started acting really distant from Ginny. He might be canceling their dates frequently or not being as affectionate as he used to be. In the fanfiction, Ginny might also find some strange gifts or notes that she suspects are from another girl to Harry, which makes her think he's cheating.

Maybe Ginny gets a fever after being exposed to a dangerous magical artifact. The fever makes her have strange dreams. Harry, being the hero, tries to enter her dreams to figure out what's wrong. He battles the dark forces within her dreams and finally manages to wake her up and cure her fever.

Well, one possible plot could be their daily adventures in raising their children.

They could also be involved in rebuilding Hogwarts and passing on their magical knowledge to the new generation.

Well, it could start with Harry nervously asking Ginny to meet him at the Hogwarts grounds. Maybe they go for a walk by the lake, holding hands and sharing stories. They could end up at the Astronomy Tower, looking at the stars and having a really deep conversation about their future together.

Well, perhaps the fanfic could focus on their travels. They decide to explore different parts of the wizarding world that they haven't seen before.

One possible plot could be a detailed account of their wedding day. It might start with Ginny waking up, feeling a mix of excitement and nervousness.

There could be a magical display during the vows, perhaps some floating candles and enchanted flowers. After the wedding, they could have a reception filled with dancing and laughter, and then they might go on a honeymoon to a secret, magical location.

It could be that Ginny uses a dark magic spell in a moment of anger or recklessness. Harry, being the defender of the light, punishes her by making her study the history of the harm caused by dark magic.
