The author can build tension by constantly threatening to expose Sakura's true identity. For example, having a character get suspicious and start to investigate. Another way is to create situations where Sakura has to choose between maintaining her disguise and doing what's right. If she reveals herself, she might face consequences, but if she doesn't, something bad could happen.
The story could build tension by creating a sense of helplessness. In the diary, if the girl is in a situation where she has no control, like being trapped in a haunted place. Also, the pacing matters. If it slowly unfolds events, like she starts to notice a strange smell in the house one day, and then over the next few days, other strange things occur, it builds tension. And the use of foreshadowing, like she mentions a strange dream before the real horror starts, can also build tension.
Tension can be built by introducing unexpected twists and turns. Maybe a trusted ally betrays the protagonist or a seemingly easy solution turns out to be a trap. Additionally, ratcheting up the stakes for the characters makes the story more tense.
One common plotline could be Sakura trying to fit into a boys - only group, like a sports team or a secret club. She might face challenges in hiding her true identity, such as when it comes to changing clothes or using the bathroom. Another plotline could involve her developing feelings for a boy in the group, but being afraid to reveal her true self because she thinks he only likes her as a 'buddy'. Also, there could be a plot where her secret is at risk of being exposed by a jealous rival who suspects she's not really a boy.
You can start by creating a sense of uncertainty. Make readers wonder what's going to happen next. Also, build up to important events slowly to increase anticipation.
One way is to use slow pacing and build up suspense gradually. Let the reader or viewer wonder what's coming next.
One way is through detailed descriptions. For example, describe the look in the eyes of the attackers, how their muscles tense before they make a move. Another way is by using short, choppy sentences to mimic the quickening of Ponyboy's heartbeat. Also, having the surroundings play a role, like a dark alley with no way out can really build the tension.
The author builds tension through the characters' conflicting emotions. For example, one character may be on the verge of confessing their love while the other is pulling away. This creates an emotional tug - of - war that keeps the reader on edge.
You can also use the power of the unknown. Don't reveal too much too soon. Just give hints about what might be out there. For instance, the character hears a growl, but they don't know what kind of creature it could be. Is it a wild animal? Or something more sinister? Also, create a sense of isolation for the character. If they're alone in a big, empty place, it adds to their vulnerability and the tension of the situation. And don't forget to use short, choppy sentences when the action starts to pick up to increase the sense of urgency.
One way is to introduce time pressure or deadlines for the characters. When they have to act quickly, it naturally creates tension.
One way is to create a sense of time pressure. Make the characters have a limited amount of time to achieve their goal.
