Perhaps there's a new character, an old wizard or witch who has some connection to the marriage contract traditions. They might try to persuade Harry to follow through with the contract for the sake of the wizarding world's stability or some ancient prophecy. But Harry, of course, stands his ground, and this character's attempts create more conflict and plot twists in the fanfic.
One possible character could be the person he is supposed to marry according to the contract. This character might be from an old wizarding family, and they could be initially angry or disappointed with Harry's refusal. Another character could be Harry's best friends like Ron and Hermione. They would likely support Harry in his decision, especially Hermione who is a strong advocate for free will and individual choice.
Dumbledore could also play an important role. He might be in a position where he has to mediate between Harry and the families pushing for the marriage contract. Hermione and Ron could be there as Harry's friends, offering their support and advice during this difficult situation.
The two central characters are Harry and Daphne. Harry, with his fame and unique abilities, and Daphne, who likely has her own set of skills and a distinct personality. In the context of the marriage contract fanfic, their interactions, growth, and how they deal with the situation together are what the story mainly focuses on.
In addition to Harry and Daphne, there might be other characters from the Harry Potter universe. For example, Hermione could be a friend to Harry, giving him advice about the marriage contract. Ron might also be involved, perhaps making jokes or being a bit jealous of Harry's new situation. And Daphne's family members could play important roles as they have their own interests regarding the contract.
Obviously, Harry is one of the main characters. He is likely at the center of the multiple marriage contract situation.
Hermione would definitely be one of the main characters. She would likely be very concerned about Harry and try to find a way to reverse his mental regression. She might spend hours in the library researching spells and potions to cure him.
Another character could be a fellow inmate who has been in jail for a long time. He befriends Harry and teaches him the ropes of surviving in jail.
Well, perhaps Harry might refuse the marriage contract because he has his own dreams and goals that don't align with the traditional expectations of the contract. For example, he may want to focus on his magical studies or his adventures without the constraints of a marriage. Maybe he has feelings for someone else who is not the person in the contract.
Draco Malfoy is frequently in these fanfictions. His family's status in the wizarding world and his complex relationship with Harry and his friends make him an interesting addition to a story about a marriage contract potion. Ginny Weasley can also be a main character. Her relationship with Harry in the original series can be further explored or twisted in fanfiction involving the potion.
Hermione could be a main supporting character. She might use her intelligence to help Harry and Fleur understand the legal and magical implications of the marriage contract. Ron could also be there, providing some comical relief and also being a loyal friend to Harry during this strange situation.
A group of misfit soldiers could be main characters too. They are all a bit different and don't quite fit the typical military mold. But together with Harry, they form a unique unit. There might also be a high - ranking officer who takes an interest in Harry's progress and either helps or hinders him depending on the situation.
