Well, there could be a fanfiction where Bella dyes her hair purple by accident. Maybe she was trying to use a natural hair treatment but something went wrong with the ingredients. Her friends are initially shocked but then they start to love her new look. This new hair color also catches the eye of a certain character who previously hadn't noticed her much, and it sets off a whole new series of events in the story.
It could be related to a specific event in the fanfic. For example, if she's going undercover for some mission, changing her hair color might be part of her disguise. Also, perhaps she's influenced by someone she admires and decides to copy their hair color.
She might choose blue. Blue is often associated with intelligence and mystery, which suits Hermione well. It would be a bold yet still somewhat sophisticated choice for her.
One reason could be for a disguise. Maybe she's on the run from some bad guys in the fanfiction world and changing her hair color helps her blend in better.
If it's a hair tie given to her by a friend, it could strengthen their bond. For instance, if it was from Angela, it would be a symbol of their friendship. Whenever Bella looks at it, she's reminded of their good times together, and it might make her more likely to reach out to Angela when she's having a problem, thus deepening their relationship.
Well, one reason could be a new start. Maybe she wants to break free from her old self. In some fanfictions, she might cut her hair after a big event like a break - up or a change in her life situation. It could also be a symbol of her growing independence, showing that she's not the same girl she used to be.
Shikamaru might just sigh and say something like 'What a troublesome thing to do, Naruto.' But deep down, he would also be a bit curious about why Naruto decided to dye his hair red.
Maybe he just wants a new look. Naruto is always known for his wild and adventurous spirit, so dyeing his hair red could be a way to show his rebellious side or simply to stand out more.
One possible storyline could be that the hair tie is a memento from a special day. Maybe it was from a day she spent with a loved one, like Edward in the Twilight universe. The hair tie could be a symbol of a promise they made to each other, and throughout the fanfiction, she holds onto it as a reminder during tough times.
It could make her more alluring. People might be drawn to her because of her unique feature. Her long hair could be a conversation starter, and she might attract those who are interested in her because of it. For example, a love interest might first notice her because of her flowing long hair and be curious about her.
