Perhaps the fanfiction focuses on how Lincoln gets braces and it changes his appearance. His crush could either like the new look or be put off by it at first.

For example, he might still be the one to come up with great plans for family outings or helping his siblings with their problems.
One possible plot could be that Harry gets braces during his time at Hogwarts. His friends might tease him a bit at first, but then they get used to it.

Hermione would definitely be one of the main characters. She could be the one to research all about braces in the wizarding library to see if there are any magical implications or ways to make the process easier for Harry. And she would offer him lots of advice and support.
His sisters could be main characters. For instance, Lori might give him some advice on how to deal with the braces since she's the eldest and has more experience. Or Leni could be there to offer some fashion tips to make him feel better about his new look with the braces.
Sakura, being the kind - hearted and practical one, would immediately start giving Naruto advice on how to keep his braces clean. She might also tell him about the foods he should avoid so that the braces don't get damaged. Sasuke, on the other hand, would be his usual aloof self. However, if any other village kids were to make fun of Naruto because of the braces, Sasuke might subtly step in and intimidate them. Shikamaru would likely grumble about Naruto's new look adding to the chaos in their group. But deep down, he would understand that it's just another thing that makes Naruto unique.

Ron would also be a main character. He might start off by making fun of Harry's braces, but then he would stand up for Harry when some of the Slytherins start to bully him because of it.
