Another concept could be a magical or supernatural 'kidnap love fanfiction'. The kidnapper could be a supernatural being, like a vampire or a werewolf. He kidnaps the human he loves because he wants to protect them from other dangerous supernatural creatures. But the human doesn't understand his motives at first and struggles against him. As time passes, they develop a strange and intense love relationship.
One idea could be that Harry is under a dark spell that makes him kidnap Muggles, but then his friends try to break the spell and save him and the Muggles. Another could be that it's a case of mistaken identity and Harry is wrongly accused of kidnapping Muggles when he was actually trying to protect them from a real threat. Maybe in the fanfiction, Harry kidnaps Muggles to show the wizarding world how wrongly Muggles are treated by some wizards.
One idea could be that Scabior kidnaps Hermione to use her knowledge for some dark wizard's plan. Maybe he's been promised a great reward. Another could be that he mistakes her for someone else at first but then realizes her true value.
One alternative could be a story about the Dragonborn going on a quest to discover their true heritage. They could travel across different lands, meet various characters who help or hinder them in their search for knowledge about their family and their unique powers.
One plot idea could be that Draco and Blaise kidnap Hermione as part of a misguided attempt to gain some sort of leverage in the wizarding war. Maybe they think they can use her knowledge to find a way to end the conflict on their terms. Another could be that they believe she has a hidden power or secret that they want to uncover for their own gain. For example, they might think she has a connection to a powerful magical artifact that they are desperate to get their hands on.
In some fanfiction of this kind, the monkeys might kidnap a human because they think the human is a key to unlocking a hidden treasure or ancient knowledge. They see the human as having some unique quality like intelligence or intuition that they lack. So they take the human to their secret lair in the jungle and try to communicate with them to get what they want.
A great idea for a Theory of Love fanfiction is to delve into the backstories of the secondary characters and how their stories intersect with Third and Khai's love story. For instance, Two and Un's relationship could be explored more deeply and how it has an impact on Third and Khai. Maybe Two has some advice for Khai based on his own experiences in love. Additionally, you could write about a misunderstanding that is much more complex than in the original story, like a miscommunication that involves multiple characters and it takes a long time for Third and Khai to resolve it, which tests the strength of their relationship.
Well, you could write about two immortals who have known each other for centuries but only fall in love after a series of events that make them see each other in a new light. Maybe they were enemies before, but now they discover that their ageless existence is more meaningful when they are together. It could involve battles, reconciliations, and a deep exploration of their eternal feelings.
Another interesting concept is a love potion that is made from very rare and magical ingredients. The search for these ingredients could be a big part of the story. The main character could be on a quest to find the final ingredient to complete the love potion, and along the way, they discover secrets about love and themselves.
Perhaps a story where a character loses their love due to a misunderstanding, but then through a series of events, they are brought back together. It could involve self - discovery for both characters, realizing that their love was always meant to be, and they have to love and love again after learning from their past mistakes.
One possible plot could be that the Avengers mistake Percy Jackson for a dangerous threat. Maybe they've been given false information about his powers being uncontrollable. So, they decide to kidnap him to keep the world safe. But once they have him, they start to realize that he's not what they thought. Percy, being a hero in his own right, tries to convince them that he's on the side of good.
