Jaune could be a character created specifically for this fanfiction. Maybe he's a hero - in - the - making who is just starting to discover his abilities but is held back by his fear of funus.
Winter might become more open and less rigid. Being married to Jaune, who is more carefree, could encourage her to let loose a bit and show her softer side more often. For example, she might start to enjoy simple pleasures like picnics, which she never considered before.
One possible plot idea could be their journey of building a life together. They might face challenges from their different backgrounds. For example, Winter's strict military upbringing and Jaune's more laid - back nature could lead to some comical and also touching moments as they learn to understand and adapt to each other.
There are likely some out there. You can start by checking popular fanfic websites like Archive of Our Own. Just search for 'female Jaune Arc x male' in the search bar, and you might find some interesting stories.
It could be that Jaune has some sort of traumatic past experience with funus, which makes him scared. Maybe he witnessed its destructive power or had a personal encounter that left him with deep - seated fear.
Jaune is the character who has been expelled, so he is central to the plot. His character might be dealing with feelings of betrayal, confusion, and a desire to clear his name. The OC, on the other hand, could be a very unique individual. They might have their own goals and motives that initially seem separate from Jaune's situation. But as the story progresses, their paths become intertwined. For example, the OC could be a healer who decides to help Jaune because they sense his innocence, and their relationship develops from there.
One reason could be the novelty of the pairing. It offers a different take on the relationships within the story's universe. People are often drawn to unique pairings.
Rather than engaging with potentially inappropriate fanfiction, it's better to look for fanfiction that promotes positive values, such as friendship, teamwork, and character growth in the context of the Jaune and Ruby relationship.
Another way is that his fear could be exploited by some antagonist in the story. They might use his fear to manipulate him into doing things against the Faunus. This would create a lot of conflict and drama in the fanfiction. As the story progresses, Jaune X might then realize he has been used and start to change his view of the Faunus.
