Using a slow build - up to the moment of hurt can be effective. The writer can show Sam gradually being pushed to his limit, and Bella being unaware of the impending danger. Then, when the hurt occurs, it's like a bomb going off. And by leaving the resolution uncertain for a while, keeping the reader on edge about whether Sam and Bella will be able to fix their relationship or not.
One common plotline could be Sam losing control of his wolf side and accidentally hurting Bella physically. This might lead to a rift in their relationship and a struggle for Sam to regain Bella's trust. Another could be emotional hurt, like Sam making a decision that goes against Bella's wishes in a way that makes her feel betrayed.
Writers can start by establishing a strong emotional connection between the reader and Belle. Let the readers feel her pain and fear when Gaston hurts her. Then, introduce unexpected twists. For instance, maybe Gaston has a change of heart for an unexpected reason. Also, use dialogue effectively. The conversations between Belle and Gaston can reveal a lot about their characters and the situation. And don't forget about the side characters. Their reactions to what's happening can add depth to the story.
Writers often create tension by putting the characters in dangerous situations. For example, if Sakura travels back in time and is discovered by the wrong people, like enemies of the village, it immediately creates a tense situation. Her life could be in danger, and she has to rely on her wits and whatever skills she has to survive. Another way is by creating a race against time. Maybe Madara is about to make a decision that will have disastrous consequences in the future, and Sakura has only a limited amount of time to stop him.
Another way is to have the character's upset tummy be a result of something they did wrong, like stealing food and now they are suffering the consequences. This creates an internal conflict within the character as they deal with both the physical pain and their guilt, which adds to the overall tension of the fanfiction.
The relationship can be developed through shared experiences. For example, they could have a common hobby like reading. They can discuss their favorite books and exchange ideas, which deepens their connection. Another way is through facing difficulties together. If one of them gets sick, the other takes care of them, showing care and love.
Yes, they can be considered soulmates in certain fanfictions. Fanfiction gives authors the freedom to explore different relationships. Writers might emphasize their shared experiences in the werewolf/vampire world, or create a backstory that binds them together on a spiritual level, making them seem like soulmates.
Guilt is a very common theme. Since Sam and Dean have a strong bond, when Sam hurts Dean, he often feels intense guilt which drives the plot forward.
Sam could be just an ordinary guy who loves exploring the woods. He might be a nature enthusiast who spends his free time in the forest, and one day he just happens to come across Bella.
Another way is through the description of Taehyung's own state. If he's in pain but trying to be strong, or if he's confused and hurt by the situation, it makes the readers feel for him. The writers might also introduce some obstacles in his recovery process, like a lack of proper medical facilities or some internal conflicts within the group that delay his getting better. This all serves to create and maintain tension throughout the fanfiction.
Writers can create tension by making the body - switched Avengers face time - sensitive missions. For example, if Iron Man and Thor switch bodies and there's an immediate threat from an alien invasion. Thor in Iron Man's body has to quickly figure out how to operate the suit to fight, and Iron Man in Thor's body has to use Thor's powers effectively against the invaders. The ticking clock of the invasion adds tension.
