Well, in such fanfiction, there could be a plot where Harry tries to find a way out of the forced marriage at first. He might explore magical loopholes or seek help from his friends like Hermione and Ron. However, as time goes on, he realizes that Ginny has always been there for him and starts to accept the situation. Maybe Ginny is also dealing with her own insecurities about the forced marriage, thinking Harry doesn't really want her, but through some shared adventures or conversations, they start to build a real connection.
One possible plot development could be Harry initially resenting the forced marriage but then gradually realizing Ginny's true worth. For example, through shared adventures in the wizarding world that they are forced to embark on together, he sees her courage and loyalty in a new light.
Another development could be Ginny's perspective. She might be conflicted as well. She loves Harry, but not in this forced way. So she could be torn between her feelings for Harry and her own sense of independence. She may start to rebel against the idea too, which could lead to some interesting interactions between her and Harry as they both deal with the situation.
One possible plot twist could be that it's all a part of a dark wizard's plan to gain control over the wizarding world through their union. Maybe the dark wizard has some ancient magic that can be harnessed only if Harry and Ginny are married against their will. Another twist could be that it was a misinterpreted prophecy that led to this forced situation, and as they struggle against it, they discover new aspects of the prophecy that change everything.
One possible plot development could be that Harry tries to find a way to escape the marriage. She might use her magical skills and the help of her friends to break free from Voldemort's control. Another could be that she pretends to go along with the marriage while secretly planning to undermine Voldemort from within.
Perhaps there could be a magical object or spell involved that is causing this forced marriage. Harry and Snape might have to work together to find and break this spell. Along the way, they could learn more about each other's pasts and secrets, which could change their relationship from one of enmity to something more complex.
Perhaps the main antagonists are some of the old - fashioned wizarding council members who believe in arranged marriages for political stability. They force Harry into the marriage with Ginny without considering their feelings, and they would oppose any attempts by Harry and Ginny to break free from the forced union.
In such a fanfiction, there might be political reasons for the forced marriage. For example, to unite two powerful clans or villages. Naruto and Sasuke then have to navigate the complex political web while dealing with their own feelings. Sasuke, who is often more reserved, might struggle with opening up to Naruto in this new context. Naruto, on the other hand, might try to bring his positive energy into the relationship and slowly break down Sasuke's walls.
Perhaps Caroline tries to find a way to break the forced marriage. She might seek help from her friends or allies in the fanfiction world. They could come up with a plan that involves some sort of magical or political solution to free her from the obligation.
One possible plot development could be Katara initially resisting the marriage wholeheartedly. She might try to escape or find a way to nullify the forced union. This could lead to a lot of tension between her and Zuko, as he may be more accepting of the situation due to political or family reasons.
In some cases, it could be the Ministry of Magic itself. If the Ministry is under the control of corrupt officials, they might force the marriage for their own political gain. They could use Harry's popularity and Ginny's family connections to further their own agendas, and thus become the antagonists that Harry and Ginny have to fight against in the fanfiction.
