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.
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.
By using descriptive language about the attack. If the writer vividly describes the attacker's menacing appearance, like 'The dark - cloaked figure loomed over Hermione, its eyes glowing red as it raised its wand menacingly', it makes the situation seem more dire. Also, showing Hermione's fear and vulnerability, such as her hands shaking as she tries to reach for her wand, adds to the tension.
One good example could be a story where a character has an upset tummy after eating some bad food at a fair. The author might describe the character's discomfort in detail, like the queasy feeling in their stomach and the need to constantly find a restroom. It could also involve other characters helping them through this difficult time.
By showing the severity of the injury. If a Charizard has a badly broken wing, it immediately creates tension as the reader wonders if it will ever fly again. The uncertainty of the Pokémon's future makes the story gripping.
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 way is through the reactions of the other characters. If the village leaders start to question whether Naruto can still be a useful ninja, it creates tension. And if his friends are divided on how to help him, that also adds to it. Another method is by introducing new threats that specifically target Naruto because of his weakened state due to his breathing problem. Maybe there's a group that wants to take advantage of his vulnerability.
Writers can create tension by having the fungal infection spread quickly. If it starts infecting more and more characters at a rapid pace, the remaining characters will feel pressured to find a solution fast. For example, if a whole village gets infected overnight, the RWBY team will be in a race against time.
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.
Another way is through the setting and external factors. In a Chinese fanfiction, the social or family background might be a big factor in the forced love. If a family forces two characters together, the pressure from the family and the characters' attempts to deal with it can build up a lot of tension. Also, secrets within the forced relationship can add to the suspense and tension.
By showing unequal treatment. For instance, if one sibling is given a rare Pokemon while the other gets a common one. This immediate difference in resources can create tension. Another way is through the use of dialogue. Snide remarks or passive - aggressive comments between the siblings can heighten the tension.
