Perhaps in the fanfiction, there is a prophecy that states Percy and Hera must come together in a union for the greater good of the world. They initially resist due to their past differences. Percy might be hesitant because of Hera's past actions towards him and his friends. But as they interact more, they discover new sides of each other. Hera could be shown to have a more vulnerable side that Percy comes to appreciate, and they gradually fall in love while trying to fulfill the prophecy.
Well, a plot might involve Percy being under a spell that makes him see Hera in a different light, and Hera, being intrigued by Percy's unique nature, they start to develop feelings. This could lead to a complex relationship where they have to deal with the consequences of their actions within the context of the fanfiction world. Maybe they have to keep their relationship a secret from the other gods and demigods, adding a layer of secrecy and tension.
One possible plotline could be the shock and chaos that ensues within the demigod world when they find out about Hera being pregnant with Percy's child. There would likely be a lot of disbelief and political unrest as Hera is a goddess and Percy is a demigod.
One possible plotline could be that they start as friends who gradually discover deeper feelings for each other. They might be on a quest together and during the challenges, they rely on each other more and more, leading to a romantic connection. Another could be that they meet in a time of crisis in the demigod world. With the chaos around them, they find solace in each other and their relationship blossoms from there.
Maybe the mortal has a special talent, like being an amazing poet. Hera, who is used to grandeur in Olympus, is charmed by the mortal's simple yet profound words. This leads to her falling for him, but she has to hide it from the other gods as it goes against the norms of the divine world.
In general, it can be a bit controversial. In the original context of the Percy Jackson series, their relationship is not of that nature at all. It might make some fans uncomfortable as it goes against the established character relationships. However, in the realm of fanfiction, different interpretations are allowed as long as they are not promoting harmful or inappropriate values.
One common plotline could be Hera trying to manipulate Percy's relationships with others. For example, she might try to keep him away from Annabeth to assert her possessiveness. Another could be Hera interfering in Percy's quests, not to help him but to keep him under her control.
One possible plotline could be Percy and Hera having to work together on a quest. Maybe Hera is forced to rely on Percy's unique skills and they start to build a grudging respect for each other. They could face various mythical creatures and challenges along the way, and through their shared experiences, they learn more about each other's true natures.
A plotline could involve some sort of magical or supernatural influence that makes Percy and Nico's feelings for each other more intense. They might be under a spell that heightens their emotions, and this leads to them making out. Then, they have to figure out if their feelings are real or just a result of the magic while also dealing with the reactions of their friends and the wider demigod community.
It could be that Hera is a powerful spirit or goddess in the Naruto universe who has been awakened. She sees potential in Naruto and decides to train him to reach his full potential. The plot might include Naruto facing challenges within himself as he tries to master the new skills Hera teaches him. There could also be a sub - plot where other ninja clans become suspicious of Naruto's new powers and training, leading to some conflict.
In some fanfiction, it could be that making love is a way for them to heal each other's emotional wounds. Vincent, with his complex past, might find solace in Catherine's love. Catherine, on the other hand, could feel more complete. After this, they could decide to be more public about their relationship within their community, which would bring both support and some resistance, but they would face it together because of the new level of connection they have achieved.
One possible plotline could be that Percy has been betrayed by his closest friend. Maybe this friend revealed a big secret of Percy's, and now Percy feels isolated and heartbroken. He might start to question his relationships and his place in the world.
