One possible reason could be that in the context of the fanfiction, Hera is tired of Zeus' constant infidelities. She might have reached a point where she just can't bear to deal with him anymore, so she chooses to ignore him as a form of self - protection.
The relationship changes in terms of emotional connection. Hera's ignoring Zeus might mean that the emotional bond that was there (even if it was a tumultuous one) is starting to break. This could have far - reaching consequences in the fanfiction world, like affecting the balance in the pantheon or causing other gods and goddesses to take sides depending on how they view Hera's actions towards Zeus.
Hera was Zeus' wife. Her main role was to be the queen of the gods. But in their relationship, she was often the one trying to keep Zeus in check due to his many affairs.
Perhaps in a fanfiction, Zeus, in a fit of anger over Hera's interference in one of his mortal affairs, uses his power to ostracize Hera from the other gods for a time. This makes Hera feel isolated and hurt, and she has to find a way to regain her standing while also dealing with the betrayal of her husband. It could show her strength as she overcomes this difficult situation.
It could be a mortal man. In Greek mythology, gods sometimes had affairs with mortals. Maybe a particularly handsome and charming mortal catches Hera's eye. He might be a great hero or a simple shepherd with a pure heart.
Zeus was powerful and dominant. He was the king of the gods and had a lot of freedom in his actions, which unfortunately often included being unfaithful. Hera was strong - willed and jealous. She couldn't tolerate Zeus's affairs and would fight back.
In this fanfiction, Naruto's appearance might be different. Since he is the son of two powerful gods, he could have a more majestic look. His eyes might glow like lightning or have a special color. His story could involve him trying to fit in with the normal ninjas while also coming to terms with his divine parentage. He might face discrimination from some who fear his power, but he overcomes it with his kind heart, just like in the original Naruto story.
Common themes in Zeus and Hera lemon fanfiction often revolve around their complex relationship. There's the theme of passion, which is obvious considering the 'lemon' aspect. Their relationship is also marked by conflict in the mythology, so that might show up in the fanfiction as well. For example, they might have passionate arguments that then lead to a more intense connection. Also, the theme of loyalty and betrayal can be explored, as Zeus was known for his unfaithfulness and Hera's reactions to it.
I'm not sure specifically what that particular fanfic is about as I haven't read it. It could potentially be a fan - created story that focuses on the relationship between Zeus and Hera with some sort of unique or interesting twists. Maybe it reimagines their mythological relationship in a modern or different setting.
One possible plot could be Percy discovering his new parentage of being the son of Zeus and Hera. He might struggle with the new identity as it goes against what he previously knew. For example, he could face challenges from the other demigods who are suspicious or jealous of his new status. He then has to prove himself worthy of this new heritage while also dealing with the complex politics among the gods.
There is definitely some out there. One aspect that might be interesting in these fanfictions is how Percy's powers could be different since his parentage is from Zeus and Hera. In many traditional stories, Percy is a son of Poseidon, but in these fanfictions, he could have lightning - based powers or other abilities related to Zeus and Hera's domains.
