One key element is the emotional connection. Harry, having lost so much, really leans on Sirius as a father figure. Sirius, in turn, has a strong desire to protect Harry. For example, in many fanfics, Sirius is the one who consoles Harry when he has nightmares about Voldemort.
One great 'Harry x Sirius Comfort' fanfic is 'A Shoulder to Lean On'. It beautifully portrays Sirius being there for Harry during a tough time at Hogwarts. The author does an amazing job of showing their bond through simple yet powerful interactions.
Well, in these fanfics, one important element is the magic used for time travel. It could be a time - turner or some other magical device. Then there's the character development. Harry and Ginny often grow as individuals during this adventure. They become more confident and resourceful. Also, the interactions with the past versions of other characters, like Dumbledore or Lupin, are crucial as they help or hinder the rescue mission.
The magical world building is also important. A good fanfiction will incorporate the rich lore of the Harry Potter universe. For example, how the use of magic is involved in their relationship, like Sirius teaching Harry a new spell or them using magic to solve a mystery together. And of course, the story should stay true to the overall tone of the original series, which is not adult - themed but rather about adventure, friendship, and the fight between good and evil.
Character development is a significant element. Harry may start off as a bit naive in some fanfictions, but through his interactions with Sirius, he becomes more confident and self - assured. Sirius, on the other hand, may start as a bit reckless but learns to be more responsible for Harry's sake. Also, the theme of loyalty is often explored. Sirius is fiercely loyal to Harry, and this loyalty is tested in various situations in the fanfiction, such as when Sirius has to choose between his own freedom and protecting Harry.
There are quite a few. One such fanfic is 'The New Guardians' where Sirius takes Harry under his wing to protect him from new threats.
There's also 'Sirius's Guidance'. This fanfic focuses on Sirius becoming a sort of mentor to Harry in ways that the books didn't fully explore. It's full of heart - warming scenes where Sirius imparts his knowledge and experiences to Harry, and it's well - written with a lot of interesting plot twists.
Character growth is a big part of it. Fem Harry might have to grow into a more confident person in the relationship, and Sirius has to come to terms with his new role as a partner to Harry. Also, the plot often involves some sort of conflict. It could be an external threat, like Voldemort or his followers trying to use their relationship against them. Or it could be an internal struggle within the relationship, like trust issues or differences in their goals for the future.
Another theme is the healing power of friendship. Fanfics often show how the strong bond within Monsta X can help a member overcome personal insecurities or past traumas. They might have a heart - to - heart talk or just do something special to make the hurting member feel better. In these fanfics, friendship is not just about having fun together but also about being there through the hard times.
One common theme is trust. Since they are both survivors of the Hunger Games, they have to trust each other in order to find comfort. For example, Katniss has to trust Haymitch's guidance in the Capitol's political games.
There's also 'Haru's Solace in Makoto'. This fanfic focuses on Haru going through a period of self - doubt. Makoto steps in and through their shared memories and his unwavering support, he helps Haru regain his confidence. The way the author describes Makoto's calming presence and Haru's gradual transformation is really engaging.
