Daphne could be a shy and artistic girl. She might be into painting or writing, and she sees Harry as this source of inspiration. Maybe she first noticed Harry in an art gallery or a library, and that's when the crush started.
Hermione could be involved. She might suspect Daphne of having ulterior motives regarding Harry and try to warn him, which could play into the betrayal storyline in some way, either as a catalyst or as someone who helps Harry deal with the betrayal later.
In this fanfic, Harry would likely grow in his social skills. Since Daphne has different social circles, he'd be introduced to new people and ways of interacting. He might become more diplomatic, learning from Daphne how to handle different personalities gracefully. Daphne would develop a stronger sense of loyalty. As she gets to know Harry better, she'd see his unwavering loyalty to his friends and causes, and this would inspire her. She might also become more adventurous, as Harry often gets into exciting (and sometimes dangerous) situations, and she'd be drawn into them, expanding her own boundaries.
Hermione would probably be in it. Since she's Harry's best friend, she might offer her intelligence and advice to Harry and Daphne in their post - war endeavors. Maybe she helps them with research or legal matters if they're trying to change things in the wizarding world.
Their relationship could be one of mutual protection. Harry, with his heroic nature, would always be ready to defend Daphne. And Daphne, being intelligent and resourceful, could offer her own kind of support to Harry, like helping him with his studies or providing advice in tricky situations.
The relationship could develop through shared interests. Say they both have a passion for ancient magic. They start discussing it in the library, and as they do, they find themselves drawn to each other more and more. Their conversations grow deeper, and before long, they realize they're in love. Harry might share his experiences with Voldemort with Daphne, and Daphne could open up about her family's expectations. This mutual sharing of personal and difficult things would strengthen their bond.
Some fanfictions might include Luna Lovegood. Her unique personality and magical insights could add an interesting dimension to the harem. She could be the one who brings a sense of calm and otherworldly wisdom to the group.
One great 'Harry Daphne Fanfic' is 'The Green-Eyed Snake'. It has a really interesting plot where Daphne and Harry team up to solve a mystery in the wizarding world. Their relationship develops in a very natural way throughout the story.
Yes, in some fanfictions Daphne can be Harry's mate. Writers often create alternative pairings in fanfiction, and Daphne is a character that some authors choose to pair with Harry for various reasons, like creating new storylines or exploring different character dynamics.
Harry might become more confident and decisive as he has a second chance to make things right. He could use his past experiences to be bolder in his actions. Daphne, on the other hand, might develop a stronger sense of adventure. Going back in time is a huge change, and she may grow from being a more reserved Slytherin to someone more open - minded and勇敢.
