One positive way is to explore her friendships. Write about her interactions with other characters, how they support each other, and the adventures they go on together. It could be a story of loyalty and teamwork among friends in the world she inhabits.
Another great approach is to give her a new mission or goal. It could be something related to the overall plot of the original work but with a fresh perspective. For instance, if there are issues in her world like a new threat or a mystery, she could be at the center of trying to solve it, showing her intelligence and determination.
One idea could be exploring Willow's past relationships and how they shaped her into the person she is in the RWBY universe. Maybe she had a close friendship in her youth that was torn apart by the power struggles in Atlas.
One interesting RWBY Willow Schnee fanfiction could be about her past and how she ended up in her current situation in the Schnee family. It might explore her relationships with other family members like Weiss and Jacques. Another could be a story where Willow discovers a hidden power within herself and uses it to break free from the constraints of the Schnee family's reputation and expectations.
You can focus on their friendship. For example, write about how they train together, share their experiences from different battles, and support each other emotionally.
You can focus on their adventures together. For example, write about a new quest they embark on, how they use their unique skills and powers to overcome challenges. This way, it stays true to the adventurous nature of the original story.
You can focus on her character growth.

One positive way is to write about their personal growth. For example, Nick's journey in coming to terms with his identity and how Charlie supports him through it. You can also write about their experiences at school, like how they deal with bullies together or their study sessions.
One positive approach could be to write about their relationship in a more platonic and heartwarming way. For instance, they could be volunteering at a local shelter together. Darcy could be great with the animals and Logan could be helping with the building repairs. This type of story shows their kind sides and the bond between them without any inappropriate content.

Write about his journey in the acting world. Maybe a fanfic about how he prepared for a difficult role, his experiences on set, and the relationships he built with his co - actors. It would be a great way to show respect for his work and talent.
