One possible plot twist could be that at first, Hermione and Severus despise each other due to their past differences. For example, Severus has always been rather cold towards Gryffindors, and Hermione is a proud Gryffindor. But as they are forced to spend time together because of the arranged marriage, they start to discover each other's hidden depths. Hermione might find Severus's intelligence and his complex past with Lily fascinating. And Severus could come to respect Hermione's quick wit and thirst for knowledge. Another plot twist could be that there is some external force trying to break up the arranged marriage. Maybe some dark wizards see it as a threat to their plans, or there are those in the wizarding world who oppose the union of a Muggle - born like Hermione and a former Death Eater like Severus.
One plot idea could be Hermione and Severus initially hating the idea of the arranged marriage. Hermione might try to find a way out while Severus is conflicted between his past prejudices and the new situation. As they are forced to spend time together, they gradually discover each other's hidden depths. For example, Hermione realizes Severus's great knowledge of the Dark Arts which he can use to protect her in a dangerous situation, and Severus comes to respect Hermione's intelligence and courage.
In the beginning, Hermione might be the one trying to make the best of the situation. She would try to communicate with Severus, but he would probably push her away. However, as they are forced to live together and share responsibilities, they would gradually open up. Maybe they would start having conversations about magic, books, and their past experiences. Slowly, a bond of mutual understanding would form, and their relationship would develop from one of hostility to something more like friendship, and eventually, it could turn into love.
Well, a plot twist might be that the Marriage Law is actually part of a dark wizard's plan. Hermione and Charlie then find themselves in the middle of a much larger conspiracy. They might have to use their unique skills - Hermione's intelligence and Charlie's dragon - handling knowledge - to expose the plot and in the process, their relationship could either strengthen or face challenges. Also, perhaps there are ancient magic rules related to such marriages that they need to figure out.
Well, a plot twist could be that the arranged marriage is actually a ploy by an enemy. They plan to use Naruto and Hanabi's union to create chaos in Konoha. Naruto and Hanabi start to suspect something is off and have to work together to figure out the real plan behind their arranged marriage. It could lead to them developing a real bond in the process of uncovering the conspiracy.
Perhaps a plot twist could involve a mystery related to the arranged marriage itself. It could be that there was a hidden prophecy or an ancient magical pact that led to their arranged union. As Draco and Luna try to figure out the true reason behind their marriage, they uncover secrets about their families and the wizarding world that no one else knew. This discovery could either strengthen their bond as they face these revelations together or put a strain on their relationship as they struggle to come to terms with the new - found knowledge.
One possible plot twist could be that Naruto initially resists the arranged marriage because he's still hung up on his feelings for Sakura. But as he gets to know Shizuka, he discovers she has a lot in common with him in terms of her ninja skills and values. For example, she might be really good at a particular jutsu that Naruto respects. Another twist could be that Shizuka has a secret mission that she can't tell Naruto about at first, and this creates tension in their relationship. As for a third twist, perhaps there's a rival from Shizuka's past who shows up and tries to break up their arranged marriage.
Maybe there's a plot twist where Sakura discovers that Neji was forced into the arranged marriage against his will. This could lead to her trying to find a way to break the arrangement in a way that doesn't cause too much trouble for their families or clans. However, in the process, they start to develop real feelings for each other.
One possible plot twist could be that Naruto initially resists the arranged marriage because he has feelings for someone else, like Sakura. But as he gets to know Kushina, he discovers that they have a lot in common. For example, they both have a strong will and a love for their village. This could lead to a slow - burning romance where they gradually fall in love.
One possible plot twist could be that Percy and Thalia initially resist the arranged marriage. Percy might be in love with someone else, like Annabeth. But as they are forced to spend time together for the sake of the arranged union, they start to discover each other's hidden qualities. Thalia could reveal her vulnerable side to Percy, and Percy could show his loyalty and courage in a new light to Thalia. This could gradually lead to them developing real feelings for each other, despite their initial reluctance.
Well, a great plot twist could be that Marinette has a secret identity as Ladybug, and she's worried that the arranged marriage will interfere with her superhero duties. So she tries to keep it a secret from Adrien, which leads to all sorts of misunderstandings. Adrien, on the other hand, might have his own secrets related to his father's business or his own hidden talents that come to light during the arranged marriage situation. And perhaps, there's a prophecy or an old family curse that is related to their arranged marriage. It could be that if they don't fall in love and stay together, something bad will happen to the city. This would add an extra layer of drama and urgency to their relationship.
