They might describe it as a sharp pain that won't go away. For example, 'Draco clutched his stomach, a sharp pain stabbing at him like a thousand needles.'
Others may focus on his facial expressions. They could write that his face turned pale, his brows furrowed in pain, and beads of sweat formed on his forehead as his stomach ached. This shows the visible effects of the stomach ache on him.
One common plot could be Draco getting cursed and the stomach cramps being a side - effect of the curse. In fanfiction, the author might use this as a way to show his vulnerability. Another plot could be Draco eating something bad at Hogwarts and getting severe stomach cramps, leading to a series of events where other characters have to take care of him.
Writers often describe it as a tender moment. They might use words like 'gentle' to describe the way their lips meet. For example, 'Robin's lips met Starfire's in a gentle caress.'
They could be described in relation to his expressions. For example, when he's excited or about to go into a fight, a writer might say 'Naruto's sharp teeth were bared in a fierce grin'. This not only tells us about the teeth but also gives an idea of his mood and attitude at that moment. Writers may also compare his sharp teeth to those of an animal, like 'Naruto's teeth were as sharp as a wolf's, a sign of his untamed spirit'.
Some fanfiction writers describe Naruto's nightmares as chaotic. There could be a jumble of his memories, from his training days when he was constantly struggling to keep up, to the moments when he almost lost his friends in battles. The nightmares might be filled with strange noises, like the growling of the Nine - Tails mixed with the screams of his comrades. The writers also tend to show Naruto thrashing around in his sleep, sweating and muttering incoherently as he experiences these terrifying dreams.
Some writers might describe it as a gentle, hesitant touch of lips at first. Like 'Their lips met softly, as if testing the waters, a delicate exploration.'
Writers often start by exploring their canon personalities. For Hermione, her intelligence, determination, and strong sense of justice are key aspects that are carried over. They might then add some vulnerabilities, like her insecurities about her Muggle - born status in a relationship with Draco. For Draco, his Slytherin pride and family loyalty are usually part of the foundation. Then, they might show his internal conflict as he falls for Hermione, which goes against his family's values.
Some writers might describe it as a hesitant kiss. Katniss, being a guarded character, might be tentative at first. So the kiss could start softly and gradually build in intensity as her feelings surface.
Some writers might describe Naruto's dense muscles as being like cords of steel. They could say his biceps bulge like hard rocks when he flexes.
Many fanfiction writers will detail the emotions that flood through them at that moment. Austin might feel a rush of excitement and a sense of finally getting what he's secretly desired for a long time. Ally, on the other hand, could be feeling a bit nervous but also a deep sense of connection. The kiss might be described as a slow - motion event, with every second of the lip - to - lip contact carefully detailed, from the initial touch to the lingering after - feeling.
