Fans like it because it gives a sense of closure. In the original series, their relationship was left somewhat open - ended. Fanfictions where they are married fulfill the fans' desires for them to be together in a more permanent way.
One popular one could be 'A New Beginning' where they start their married life on a new planet, facing all kinds of adventures together. It's full of their typical banter and sweet moments.
A great idea for this fanfiction could be that Rose starts having dreams about their future child. These dreams could give them clues about the baby's purpose or the challenges they will face. The Doctor would be very interested in these dreams and try to analyze them scientifically.
In the fanfiction, Rose's pregnancy could be a catalyst for the Doctor to finally settle down in one place for a while. Maybe they find a peaceful planet where they can build a home and prepare for the arrival of the baby. Their friends from their adventures might come to visit and offer their support. It could also lead to some interesting cultural clashes as they combine their different upbringings and knowledge to raise the child.
Well, for one thing, Ezra and Sabine have a great dynamic. They've been through a lot together in the Star Wars universe. In fanfictions, their love story can be a way to show how they can heal and grow with each other. Also, it gives fans a chance to see a different side of their favorite characters. It's like seeing them in a more personal and emotional light, which is really appealing.
Some fans like it because it offers a different take on the relationship between the two characters. In the original Harry Potter series, they are mostly at odds, and this kind of fanfiction allows for a more complex and unexpected dynamic.
It's also a very emotional moment. Naruto has been through so much, and Kurama has been a part of his journey. The hug is a way for fans to see Naruto showing his gratitude and love towards Kurama. It's a tender moment in the often action - filled Naruto universe. And it gives a sense of closure to their complex relationship.
Adventure is another theme. Since they travel through time and space together, many fanfics have them going on all sorts of exciting adventures, whether it's saving a planet or exploring a new era. It adds to the overall charm of their relationship as they face these challenges together.
One reason is that fans are often drawn to the idea of a 'what - if' scenario. In the original story, Hermione ended up with Ron. But for some, the idea of Harry and Hermione getting married is more appealing. They see Harry's courage and Hermione's intelligence as a great combination for a married couple. So, they write fanfictions to explore this alternative relationship. It also allows them to expand on the wizarding world and add their own unique elements to it based on this different relationship dynamic.
Some fans like the 'Naruto loves Anko' concept because it's a fresh take on the Naruto universe. It combines two characters that don't have a traditional romantic connection in the original series. Naruto's energetic and optimistic nature paired with Anko's more mysterious and edgy personality creates an interesting dynamic.
Well, it can also create interesting storylines. For example, it can lead to love triangles or internal conflicts within the group of friends. Fans enjoy seeing how these new dynamics play out and how they can change the overall narrative of the Naruto world. It's a fresh take on the characters we already know and love.
