Perhaps they are characters in a modern - day wizarding world where they are both part of a secret magic society. Edward could be a powerful wizard from an old family who feels threatened by Harry's new - found powers. So, he decides to break Harry's heart to assert his dominance.
One popular theme is romance. Fans often write about Harry Styles falling in love with an ordinary person, creating a sort of fairy - tale love story. Another theme is adventure, where he might be on a journey around the world or through a magical realm. Friendship is also a theme, showing his relationships with his bandmates or new friends in a fictional setting.
One sad part of Harry Styles' story could be the intense public scrutiny he has faced throughout his career. He was constantly in the spotlight from a young age as part of One Direction. This kind of extreme attention can be really overwhelming and isolating at times. It means every little thing he does is dissected and judged by millions of people.
Some popular ones might include those where the author reimagines Harry in different historical settings. For example, a story where he's a knight in medieval times. Another could be a modern - day AU (alternate universe) where he's not a singer but a college student dealing with normal college life problems while still having his charming personality. And there are often those that explore his relationships with other characters in a really in - depth and emotional way.
Twilight has nothing to do with Harry Styles fanfics. It was created by Stephenie Meyer as an independent novel series with its own unique story and characters.
It could be trending because it features a new take on Harry Styles' personality or it offers a fantasy storyline that fans haven't seen before. Also, good promotion and word-of-mouth can contribute to its popularity.
