I really like the one - shot 'Percy's Dream'. It delves into Percy's mind and his dreams, which are often filled with prophecies and memories of his past adventures. The way the author describes the hazy, dream - like state and how Percy tries to make sense of it all is very engaging.
The length of manga one shots can vary a lot. Some might be as short as 20 pages, while others could go up to 80 pages. It really depends on the story and the author's style.
First, you need to have a clear understanding of the characters involved. Know their personalities, desires, and backstories. This will make the sexual encounter in the one - shot more believable.
One interesting BTS one - shots fanfic could be those that explore the members in a fantasy world. For example, a story where they are all knights on a quest to save a magical kingdom. Another could be a modern - day AU (alternate universe) where they are college students dealing with normal life problems but still having their unique BTS - like bond.
One interesting RWBY one - shot fanfiction could be the ones that explore the backstories of minor characters. For example, there might be a story about a random student at Beacon Academy who has their own dreams and struggles. Another great one could be those that focus on alternative universes, like a world where the Grimm are the good guys. And there are also some that center around a specific relationship in RWBY, such as a deep exploration of the friendship between Blake and Yang.
There's also 'Seven Days'. This one - shot is a sweet and simple love story between two boys. It shows how a simple week can change the relationship between two people and how they slowly fall in love with each other in a very natural way.
The theme of the gods' interference also pops up a lot. In some one - shots, the gods play a role in the demigods' lives in unexpected ways. Maybe Zeus sends a thunderbolt that causes chaos in Camp Half - Blood, and the demigods have to figure out how to deal with it while also dealing with their normal daily challenges.
There's also 'Hermione's Influence on Snape'. This one - shot is all about how Hermione's presence starts to change Snape. It's a more character - study - type of fanfiction. It shows how Hermione's determination and kindness can slowly break down Snape's walls, and it's a very heartwarming read.
I'd recommend 'Peter Parker's Hidden Talents'. In this one - shot, Peter discovers a new ability that has nothing to do with his spider - powers. It's a really creative take on the character. The story is short but full of interesting twists and turns.
