It could also be a magical situation. If this is set in a world with magic, Harry might discover that playing with Dora's hair has some unexpected magical effect. Maybe it unlocks a hidden power within Dora or reveals a secret about their shared past. This simple act could then be a catalyst for a much larger and more exciting plot within the fanfiction.
Perhaps they are in a tense situation. Dora is scared or worried, and Harry plays with her hair to comfort her. It's a way of showing that he's there for her. He might be trying to soothe her nerves by this gentle gesture, and it could lead to them relying on each other more in the story as they face whatever challenges are coming their way.
It might strengthen their relationship. Physical touch like playing with someone's hair can create a sense of intimacy. So, it could make them feel closer to each other and more trusting.
Maybe they go to a wizarding cottage in the countryside. They explore the nearby magical forests together, discover new magical creatures, and Ginny could teach Harry some new Quidditch tricks in the large open fields around the cottage. And of course, they have cozy evenings inside, cooking together and snuggling up by the fireplace.
Perhaps in the fanfiction, Naruto lets his hair out when he is in a moment of deep emotional turmoil. He's tired of always conforming to the shinobi norms and decides to let his hair down as a sign of rebellion. This could lead to interesting interactions with his friends and mentors, who might be surprised or concerned about this new look and attitude.
One possible scenario could be that it's a moment of unexpected tenderness. Maybe they are in a situation where they have to put aside their differences, like during a truce in Hogwarts. Draco, being the one to brush her hair, might be a sign of his growing feelings towards Fem Harry that he doesn't quite understand yet.
Well, one possibility could be Itachi as a wizard in the Harry Potter world. Maybe he'd be in Slytherin due to his cunning nature. He could use his Sharingan abilities in a magical way, like seeing through invisibility cloaks or detecting hidden spells.
One possible scenario could be for a disguise. Maybe Harry needs to blend in among Draco's group for some sort of undercover mission at Hogwarts. Another could be as a result of a magical mishap, like a spell gone wrong in a transfiguration class that swaps their clothes. Or perhaps it's part of a bet or dare within the fanfiction's plot.
One possible scenario could be them renovating their home at the Burrow. They might be adding new rooms for their future family. Ginny could be using her magic to make the place more cozy while Harry helps with the physical labor, like moving furniture with a levitation charm.
Another possibility is that they would take a stroll in the moonlight around their new home. They would hold hands and reminisce about their adventures at Hogwarts. Harry might tell Ginny how much he loves her all over again, and Ginny would respond with sweet kisses, and then they would go back inside to have a warm drink and cuddle by the fireplace.
In some fanfictions, the kiss could be a spur - of - the - moment thing during a dangerous situation. They are so relieved to be safe that they kiss without thinking much. Then they are both a bit embarrassed but also secretly happy.
In some fanfictions, Harry might become a very influential Auror, traveling around the wizarding world to fight dark magic remnants. He could also be involved in reforming the Ministry of Magic, ensuring fairness and equality for all magical beings.
