It could be someone completely new, a character created just for this fanfic. Maybe he's a normal villager who has a kind heart and fell in love with Sakura when he saw her helping people in the village. He doesn't have any ninja powers but he has a great sense of humor and that's what attracted Sakura to him.
There were many versions of The Animal of Sidon, and the unadapted version might be:
1 The Xerofactor
2. The Cat in the Hat: Although this version also has an adapted storyline, its original author is HP Lovecraft, not Carl Aldern Rex.
3 The Secret Life of Walter Mitty: This version also has an adapted storyline, but the original author is George Orwell.
It should be noted that there may be some differences between these versions, so it is impossible to determine which version is the absolute original version and the version without adaptation.

It could be Hinata. In the original series, Hinata has a deep affection for Naruto. In a fanfiction, it would be a natural progression for her to be his secret fiance. Maybe they got engaged secretly to avoid some political unrest in the village.
One approach is to create situations where they rely on each other. Maybe there's a dark magic that is affecting both the elven land and the Zora domain. They have to work together to find the source and stop it. During this time, they see each other's determination and courage. Also, have them communicate their feelings honestly. If the sun elf is feeling homesick, Sidon could comfort her, and this vulnerability would bring them closer.
Well, it's hard to say for sure. While there are suspicions that some stories on '90 Day Fiance' are fake, we don't have absolute proof about Caesar's story specifically. However, considering how reality TV often works, with producers having a lot of control over the narrative, there is a good chance that parts of his story were not entirely genuine. They might have added twists and turns that didn't really happen in real life just to create more drama and keep viewers hooked.
There could be. Reality shows often have some elements that are not entirely real. In the case of '90 day fiance', some participants might be influenced by the producers to create more exciting storylines, which could lead to fake stories. For example, they might pretend to have a bigger conflict or a more intense love story than what actually exists in their real relationship.
One plot idea could be that the female sun elf is a healer who comes to Hyrule to study its unique flora for medicinal purposes. She meets Prince Sidon during an event where he is injured. She heals him, and from there, a friendship forms that gradually turns into a romantic relationship as they discover each other's cultures. For example, she could teach him about elven magic, and he could show her the secrets of Zora domain.
