Often, in this type of fanfiction, there would be a lot of drama and tension. Yuki's kidnapper might be someone from his past who has a grudge. The Sohma family would be in an uproar. Akito might be torn between his usual controlling self and the need to save Yuki because of his importance to the family. The other zodiac members would also be on edge. They would probably gather all their resources, both human and supernatural, to find Yuki. There could be some intense moments where Yuki is in real danger, like when the kidnapper realizes he's trying to escape and threatens him physically.
In many such fanfictions, Yuki's friends would likely launch a desperate search to find him. Kyo might put aside his differences with Yuki in order to rescue him. They would follow any leads, no matter how small. For example, if there was a witness who saw the kidnapper's vehicle, they would track it down. And Tohru would be a source of emotional support for everyone involved, constantly worried about Yuki's safety and trying to keep everyone's spirits up during the search.
Well, it depends on the writer's take. Some might have Yuki use his charm and intelligence to try and outwit his kidnappers from within captivity. He could be secretly leaving clues for his rescuers. Maybe he finds a way to communicate with one of the zodiac members through some sort of psychic connection that exists between them. And the kidnapper could have some sort of vendetta against the Sohma family, seeing Yuki as a way to get back at them.
It could be a jealous rival from school. Maybe someone who's envious of Yuki's popularity and good looks. This person might have snapped and decided to kidnap Yuki to teach him a lesson.
In Kyo x Yuki fanfiction, 'character growth through each other' is a popular trope. They can learn from each other's strengths and weaknesses. For example, Yuki can learn from Kyo's more straightforward and passionate nature, while Kyo can learn from Yuki's calm and collected demeanor. 'Mutual understanding' is also a big one. As they start to understand each other better, they form a deeper bond. Additionally, the 'sacrifice for each other' trope can be seen. They might be willing to put themselves in harm's way to protect the other, which shows the depth of their relationship in these fan - created stories.
Well, it could be that in the fanfiction, Kyo gets hurt while protecting someone, perhaps Tohru. He might be facing some sort of danger like a group of bullies or a supernatural threat. His injury then becomes a focal point for character development, as he has to deal with being vulnerable and relying on others for help.
One plot idea could be that the OC is a new student at the school Yuki attends. They accidentally bump into each other in the hallway, and Yuki's polite apology makes the OC intrigued. As the story progresses, the OC discovers Yuki's secret about being a part of the Sohma family and helps him come to terms with his insecurities regarding his place in the family and among his peers.
Well, usually in such a manga, the girl is held against her will, maybe in a secluded place. There could be attempts to rescue her by friends or heroes, and lots of tension and drama along the way.
This could be a real roller coaster! Yuki and Tohru might struggle to balance parenthood with their existing lives, but also find new depths of love and strength through the experience.
It could also be a lone vampire with a vendetta against Kaname or the academy. This vampire might think that by kidnapping Yuki, they can exact revenge on Kaname or cause chaos within the academy. Yuki is an important figure in the Vampire Knight world, and her kidnapping would surely disrupt the delicate balance that exists.
The first thing that might happen is chaos among those who know Ben. His family would be worried sick. If the kidnappers are villains who know about the Omnitrix, they could try to force Ben to unlock all its secrets. But Ben won't give in easily. He'll fight back using whatever means he can, even if he's restrained.
Well, Dean would probably go into full - on search - and - rescue mode. He'd start by reaching out to all their contacts in the hunter community. Maybe he'd call Bobby in spirit form if he could, asking for any leads or advice. He'd also check Sam's last known locations and look for any signs of a struggle.
Fanfictions often change their relationship dynamics by exploring different emotional aspects. For example, in some, Kyo might show more vulnerability towards Yuki, which is a big shift from their initial rivalry. This can lead to Yuki being more empathetic towards Kyo. Another way is by changing the power balance. In the original, they had a certain power dynamic, but in fanfiction, it could be reversed, like Yuki being the one to physically protect Kyo instead of the other way around.
