I don't know as I haven't read it. It could be characters from a well - known series that the fanfic is based on. Maybe it's the two main protagonists of a popular show who have a complex relationship that finally gets a soft resolution.
Without reading the fanfic, it's hard to say. However, given the title, it might be a couple. It could be a pair of original characters created by the fanfic author who are in love and are about to experience their soft epilogue. Or perhaps it's a re - imagining of an established couple from a story, where the author wants to give them a different, more tender ending.
I'm not sure specifically as I haven't read it. But generally, a 'soft epilogue' in a fanfic might mean a gentle and positive ending for the characters. It could be about a couple finally getting their happily - ever - after, or characters finding peace and resolution after a series of events.
There might also be other characters from the original series making appearances. For example, Neville could show up as a respected Herbology teacher at Hogwarts. His character development from a shy boy to a brave hero could be referenced, and he could interact with Harry and Hermione in the context of the fanfic, perhaps helping them with some plant - related magic or knowledge in their adventures.
In many 'harry potter epilogue fanfic', aside from the kids, the original characters like Harry, Hermione, and Ron also make appearances. They are shown as mentors or just as parents in the background. Sometimes, Draco Malfoy might also be included, either as an old acquaintance or as someone who has changed and is now more involved in the new generation's lives. His son Scorpius could be a key character too, interacting with the Potter and Weasley kids.
I don't know as there is not enough information. It could be two lovers, perhaps named something like Emily and James. Or it could be a single - sided love story with a main character who loves someone who is unaware or indifferent.
The children of the original characters would be likely main characters. For example, Jon Snow's (if he has any) descendants. They could inherit his sense of honor and face new challenges in the post - war Westeros.
I'm not sure as I haven't read the novel specifically. But it's likely that the main character is the girl who is the focus of the statement 'you deserve the world'. There may also be other characters like her friends who support her, or antagonists who try to hold her back from realizing she deserves the world.
There's no way to know for sure who the main characters are in this fanfic just from the title 'let my love open the door fanfic'. It could feature well - known characters from a popular series, or it could be an original take on a less - known story. The main characters could be people with special abilities, or just ordinary individuals whose love has extraordinary power. It all depends on the creativity of the author of this fanfic.
It might offer a conclusive ending for the characters and their storylines.
Katniss and Peeta would likely still be main characters. Their story is so central to the original series that it would be natural for them to continue to play important roles in the fanfiction. Maybe it could focus on them as they age and deal with the memories of the past.
Definitely the children of the original characters. For example, Albus Severus Potter could be a central figure, facing his own challenges at Hogwarts. He might have to deal with the legacy of his father.
