Well, obviously Harry Potter is one of the main characters. He is the famous wizard who defeated Voldemort and is now thrust into this unexpected situation of a marriage contract.
One interesting plot could be the initial shock and confusion among the wizarding community. Harry is often seen as a hero and his sudden marriage contract with Andromeda would stir up a lot of gossip. Maybe the story could explore how they first react to this contract, whether they resist it or start to find some common ground.
The main characters are obviously Harry Potter and Cho Chang. Harry is the famous wizard who defeated Voldemort, and Cho is his classmate who he had a bit of a romantic history with in the original books.
Well, of course it's Harry and Hermione. Harry, who has a destiny to fulfill in the wizarding world and Hermione, who supports him throughout their adventures. In the context of the marriage contract fanfiction, they are at the center of the story, with their relationship being the main focus. Their personalities, which are well - established in the original series, play a huge role in how they interact with each other in this new situation of the marriage contract.
The main characters are Harry Potter and Draco Malfoy, of course. Harry is the famous 'Chosen One' who has fought against Voldemort. Draco is from a pure - blood wizarding family, and has often been in conflict with Harry at Hogwarts.
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.
Hermione could be a main supporting character. She might offer her wisdom and support to Harry, helping him come to terms with the marriage contract. Also, she could act as a mediator between Harry and Severus at times.
Well, the two main characters are Harry, who has an 'evil' side in this fanfiction, and Daphne. But there might also be other supporting characters. For instance, Daphne's family members could play important roles. They might be concerned about her being in a marriage contract with an 'evil' Harry and try to influence the situation. Or there could be Harry's allies or enemies from his past that come into play because of this new development in his life with the marriage contract to Daphne.
For sure, Harry and Tonks would interact with Remus Lupin. Since Tonks had feelings for Lupin before, it would create a very complex situation. The Weasley family could also be part of their interactions. Molly Weasley might have strong opinions on this marriage contract. And then there are the other members of the Order of the Phoenix. They would be involved as they are all fighting against the dark forces and this marriage contract could have implications for their cause.
Well, Hermione would probably be one of Harry's supporters. She's always been his friend and would likely see the potential good in the marriage contract. She might help Harry understand Fleur better and encourage him to make the best of the situation. On Fleur's side, her sister Gabrielle could be a strong supporter. Gabrielle looks up to Fleur and would want her to be happy in this new arrangement, and she could also help Fleur adapt to any new cultural or family aspects related to Harry.
Hermione is a very common character paired with Harry in such fanfictions. Given their strong friendship in the original series, it's not a stretch to imagine a marriage contract situation between them. Their shared intellectual pursuits and adventures could form a strong basis for a relationship under a marriage contract.
