Writers can create tension by playing with the emotions of the characters involved. If one character has a panties fetish and is trying to hide it from others, the fear of being exposed can build tension. Also, if there is a situation where the access to the panties is restricted in some way, that can also create a tense situation in the story. However, again, this is a rather unusual and niche area of writing.
One way is through the use of conflict. Suppose there are different characters with different views on the panties fetish. Some may be accepting, while others are judgmental. This clash of perspectives can create tension. Additionally, the anticipation of an encounter related to the panties fetish, like when a character is waiting to see a particular pair of panties, can also build up tension. But it's important to remember that this is a very specific and not so widely accepted form of fan fiction, and it should be approached with caution as it may contain inappropriate or uncomfortable content for some readers.
They might use the element of discovery. For example, when a character is about to find out about another character's panties fetish. It can create an immediate sense of tension.
Writers create tension in erotic romance stories through the characters' internal struggles. For instance, if one character has moral or ethical beliefs that conflict with their growing sexual attraction to another. Also, external factors like family or social disapproval can add to the tension.
By using dialogue. For example, characters might have sharp exchanges where one accuses the other of being too friendly with someone else. This immediately creates a tense atmosphere. Another way is through description. Writers can describe the physical reactions of the jealous character, like clenched fists or a flushed face, which builds up the sexual and emotional tension.
They can create tension by making the possession a secret that could be discovered at any moment.
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.
One way is through pacing. They slow down the story when Naruto is at his weakest, making every moment count. They might also use flashbacks to show what Naruto has to live for, like his friends and his dreams for the village. This makes the readers more invested in his survival. And they introduce unexpected twists, like a false hope of recovery that turns out to be a trap or a new threat emerging just when it seems Naruto might be saved.
Writers create tension by making the danger seem real. They describe Naruto's injuries in detail, like his labored breathing, his weakening chakra flow. For example, if he's been stabbed, they might write about the pain shooting through his body. This makes the readers worry about his survival.
Writers can create tension by introducing a powerful enemy. For instance, a villain who can manipulate time, which would put Flash's speed and Supergirl's powers to the test. Another way is through relationship drama. If there are misunderstandings between Flash and Supergirl, like Flash thinking Supergirl doesn't trust his abilities, it can create tension.
Writers create tension by showing Sonic's pain and struggle. For instance, if he's trying to run but the injury stops him, it builds tension. Also, when his friends are worried about him, like Tails panicking as he tries to figure out what's wrong with Sonic, that adds to the tension.
Writers create tension by making Clint's injury really severe. For example, if he's poisoned, the readers will be on edge wondering if he'll survive. Also, showing the Avengers' desperation to save him adds to the tension.
