One great fanfiction could be about them going on an adventure together. Maybe they find a mysterious object and have to figure out what it is while also dealing with their growing feelings for each other.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often many stories there written by fans. Just search for their names and you'll likely find a good selection.
There's no conclusive evidence that they are in a romantic relationship. They may be good friends who have worked together and have great on - screen chemistry, but that doesn't necessarily mean they are in love.
Well, you could create an adventure fanfiction where Leo and Olivia are on a quest to save a magical land. There could be lots of action and mystery involved.
There is no publicly confirmed real - life love story between Leo Howard and Olivia Holt. They are actors who have worked together and might have a great on - screen chemistry, but as of now, there's no evidence of a romantic relationship off - screen.
Most of their interactions are within the context of their acting work. For example, when they are filming a scene where their characters are in a relationship, it's just acting. There's no off - set behavior or public statements that would lead one to believe there's a real love story. So, in essence, there are no such memorable moments that suggest a love story.
No. Writing fanfiction involving sexual content about a real person is inappropriate and unethical. It violates the person's privacy and can be considered a form of objectification.
