What is fluff in fanfiction?

In fanfiction, "fluff" refers to stories or scenes that focus on sweet, light-hearted, and often romantic moments between characters. These scenes are typically meant to evoke warm and fuzzy feelings in the reader and are often used to provide a break from more intense or dramatic plots. Fluff can include things like cuddling, kissing, hand-holding, and other affectionate gestures, but does not involve explicit sexual content. Fluff is a popular genre in fanfiction, especially in fandoms where fans enjoy shipping or romantic relationships between characters. It is often used to explore the softer side of characters and offer fans a sense of comfort and happiness.
