Maybe in the fanfiction, Felicity is kidnapped because she has some secret knowledge. Her hair in a bun is a symbol of her intelligence in this story. The kidnappers think she can unlock a powerful code or something. Her friends start a rescue mission, and along the way, they discover that Felicity has left a trail of breadcrumbs in the form of things she did with her bun, like using a hairpin from her bun to mark the path she was taken.
One idea could be that Felicity is kidnapped by a rival of her friend. Her hair in a bun might be a key detail, like the kidnapper uses it to hold her captive in some way, perhaps by tying her bun to a post. Then her friends have to figure out where she is based on the few clues she manages to leave behind, which are related to her bun.
Another scenario could be that Felicity is a princess in a fantasy fanfiction with her hair in a bun. She is kidnapped by an evil sorcerer who wants to use her for some dark magic ritual. Her bun holds a special charm that the sorcerer needs. Her loyal knights then embark on a dangerous journey to rescue her, facing many obstacles along the way.
The fact that her hair is in a bun might also play a role. It could be a cultural or traditional style in the fictional world she belongs to. When she's kidnapped, her captors might be disrespectful of this style, which angers her and gives her the motivation to resist. The bun could also be used practically during her captivity. For example, she might hide small objects in it to help her escape, like a lock pick or a small note.
In the fanfiction, Felicity with her hair in a bun might find a way to escape on her own. Since her hair is in a bun, she could use the hairpin or ribbon in it to pick a lock or create a distraction. Once she escapes, she has to evade the kidnappers' search parties while trying to find her way back to safety. Along the way, she might meet some unexpected allies who are drawn to her because of her unique appearance, including her bun.
Perhaps the black hair tie is a reminder of a past love. Felicity is constantly haunted by the memories associated with it. She meets someone new in the fanfiction, and the presence of the hair tie creates a conflict as she tries to move on from her past while still holding onto this memento.
In the fanfiction, her hair tie could be enchanted. When she's kidnapped, she discovers that she can use it to send out a distress signal only visible to those she trusts. Her bun could also hold a secret. There could be a hidden tattoo on the back of her neck that is only visible when her hair is in a bun, and this tattoo is the key to a great treasure. The kidnappers don't know this yet, but they will soon find out as the story unfolds.
Such a description might be used to make the character stand out in a fanfiction. He could be a unique character in a fantasy - based fanfic too. For example, he could be a wizard who has adapted to some modern - day human habits like wearing a hair tie on his wrist. His bun could be a way to keep his long hair out of his face while he's performing magic.
