One interesting plotline could be the discovery of the betrothal contract and how it throws Harry's life into chaos. Maybe he has to deal with a whole new set of expectations and relationships he never anticipated.
In this fanfic, a possible plotline could be centered around the relationship dynamics created by the betrothal contract. For example, Harry might be betrothed to a character he barely knows or even dislikes at first. This then leads to a journey of them getting to know each other. There could be a lot of misunderstandings and cultural clashes as they come from different backgrounds within the wizarding world. Also, it might involve other characters like Hermione and Ron trying to help Harry navigate this new situation, which could add a whole new layer of complexity to their friendships.
A third plotline might be about Harry trying to break the betrothal contract. He could feel that it's restricting his freedom and preventing him from being with the person he truly loves. This could lead to a whole adventure of finding loopholes in the wizarding laws regarding betrothals and facing the consequences of going against an old and powerful contract.
A great plot in this type of fanfiction might involve the betrothal contract being a key to unlocking some long - forgotten magic. Harry and the other character involved in the contract (let's say it's a character from a different magical school) have to work together to figure out how to use this magic to defeat a new dark threat. They start off not getting along because of the forced betrothal, but as they learn more about the magic and each other, they develop a real bond.
One common theme is the struggle against tradition. The betrothal contract often represents an old - fashioned wizarding custom that the characters have to come to terms with. For example, Harry might not be happy about being bound by such a contract in a modern - day Hogwarts.
I really liked 'The Hidden Betrothal Contract'. It's a story that starts with the discovery of a long - forgotten betrothal contract that involves Harry Potter. The author does a great job of exploring the implications of such a contract in the context of the relationships and politics within the wizarding world. It's full of twists and turns that keep you hooked from start to finish.
Obviously, Harry Potter himself would be a main character. Since it's about a betrothal contract related to him. And probably the person he is betrothed to, whoever that may be in the fanfic's universe.
One interesting plotline could be how Harry and Daphne initially react to the marriage contract. Maybe Harry is hesitant at first, but as he gets to know Daphne better, he starts to see the potential in their relationship. Another could be the challenges they face from their families and society due to the contract.
Perhaps there could be a plotline where Harry discovers secrets about the marriage contracts that change his perception of them. He could find out that they were made under false pretenses or with ulterior motives by some of the other parties.
One possible plotline could be the chaos that ensues when a marriage contract is suddenly revealed and multiple characters are involved in the harem situation. For example, Harry might have to navigate his relationships with Hermione, Ginny, and perhaps some other female characters like Luna. There could be a lot of drama as they all try to figure out their places in this new arrangement.
One interesting plotline could be the political implications of multiple marriage contracts within the wizarding world. For example, how different families use these contracts to gain power and influence. Another might be the personal relationships that develop among the characters involved in the contracts. They might start off as reluctant partners but grow to care for each other in unexpected ways.
One idea could be that the betrothal contract is used as a political tool to unite two wizarding families or factions. This might lead to Harry having to navigate complex political alliances and power plays within the wizarding world.
