Maybe the forced marriage contract was set up by a well - meaning but misinformed wizard in the past. Harry initially resists but then realizes that the person he's supposed to marry has some crucial information about his parents. So, he decides to work with her within the bounds of the contract to uncover the secrets. And along the way, they actually start to develop real feelings for each other.
A great plot twist could be that the contract is magically linked to a prophecy. Harry has to go through with the marriage to fulfill the prophecy which is related to saving the wizarding world. But the person he's supposed to marry is from a family that has a long - standing feud with the Potters. So, he has to navigate through all these complex relationships and family politics while also dealing with the threat of Voldemort or other dark forces.
A possible plot twist is that the marriage contract potion gets mixed up with another potion. So, instead of creating a marriage - bound situation, it creates a situation where the characters have to work together to reverse the wrong potion's effects. This could lead to all sorts of adventures and self - discovery for the characters as they figure out how to fix things.
One interesting plot twist could be that the marriage contract was actually a ruse by a dark wizard to gain control over both Harry and Fleur. So they have to team up to break the contract's hidden enchantments.
One possible plot twist could be that Harry discovers the marriage is part of a dark wizard's plan to gain control over him. Maybe the dark wizard wants to use Harry's fame and power within the wizarding world for their own evil deeds. Another twist could be that the person he is forced to marry is actually an undercover ally who is trying to protect Harry from a greater threat. For example, she might be pretending to be part of the forced marriage scheme but is actually working with Dumbledore's old network to keep Harry safe.
Well, perhaps a plot twist is that the marriage contract was actually a misinterpretation all along. It was originally written in an ancient magical language that was misread, and instead of a marriage contract, it was a pact for magical knowledge exchange. So, Harry and Fleur have to figure out how to deal with this new understanding and the expectations of their families and friends. It also might be that the contract was magically altered by a dark wizard long ago, and as they dig deeper into it, they uncover a conspiracy that dates back generations.
One interesting plot twist could be that the marriage is part of a dark wizard's plan to gain control over the wizarding world through Harry. But Harry discovers a hidden prophecy that gives him the power to turn the situation around and expose the dark wizard's true intentions.

One possible plot twist could be that the marriage contract was actually a ploy by an enemy to divide their wizarding families. Maybe the terms of the contract were misinterpreted at first, and as they start to fulfill it, they discover hidden clauses that put them in a difficult situation.
One interesting plot development could be the political and social fallout within the wizarding world. When Harry breaks the marriage contract, it might cause rifts between different pure - blood families who had vested interests in the union. Another aspect could be Harry's own personal growth as he defies the traditional expectations set by the contract, and he might explore new relationships or his own identity more freely.
One interesting plot twist could be that the two characters who entered the contract marriage start to develop real feelings for each other unexpectedly. This changes the whole dynamic from a business - like arrangement to a more emotional relationship.
One interesting concept could be how the marriage contract affects the relationships between the characters. For example, it might force two characters who initially dislike each other, like Draco and Hermione, to get to know each other on a deeper level. This could lead to unexpected alliances and character growth.
