Sometimes, there's a plot twist where one of them is under a spell or a curse that affects their relationship. For example, Hermione might be under a spell that makes her forget about Ron, but they are still secretly dating because Ron is trying to break the spell without anyone else knowing. This creates a lot of emotional turmoil and conflict in the story, which can be really interesting to read.
One common plot twist is that they are secretly dating to avoid the attention of the wizarding media. Since they are both friends of Harry Potter, they might want to keep their relationship private from the prying eyes of the press.
In some of these fanfictions, a great plot twist is when Hermione gets cursed and Draco has to find a way to break it. During this process, they learn more about each other's true selves. Also, it could be that Draco is under the influence of a dark spell that makes him act against Hermione, but she believes in the good in him and tries to break the spell, which deepens their bond in a very unexpected way.
One common plot twist is that Ron and Hermione are actually under the Imperius Curse. So they don't have control over their actions when they betray Harry. Another could be that they are trying to protect Harry in a very wrong way. They might think that by distancing themselves from him or even giving false information about him, they can keep him safe from a greater threat.
A common theme is the exploration of their different personalities. Ron is more laid - back and Hermione is more studious, and fanfictions often play with how they balance each other out in a dating relationship.
Another theme is dealing with outside interference. Some fanfictions explore how their friends like Harry might react to their relationship. There could be some friendly teasing or even some misunderstandings that their friends accidentally create. It adds an interesting layer of drama to the story.
Often, there's the theme of redemption. Draco, who was on the wrong side in the books, is shown to be changing through his relationship with Hermione. And for Hermione, it's about seeing the potential for good in someone she previously thought was a bully. There's also the theme of forbidden love, as their relationship goes against the norms of the wizarding world they live in.
One common theme is the secrecy aspect itself. Writers often explore how they keep their relationship hidden from their friends like Ron. Another theme could be the challenges they face due to the wizarding world's expectations. For example, there might be concerns about how it could affect their roles in the fight against Voldemort.
Well, in these fanfictions, a common plot twist is that the relationship between Ron and Lavender turns out to be a big misunderstanding. Maybe Ron was under a spell or something, and when he realizes it, he has to grovel to get Hermione back. Another plot twist could be that Hermione, in her heartbreak, discovers a new love interest who is much better for her than Ron ever was. This new character could be from a different house or even a different magical community. Also, sometimes the plot twist is that Lavender herself pushes Ron back to Hermione because she realizes they are truly meant to be together.
One possible plot twist could be that Hermione's pureblood status was hidden to protect her from a dark wizard or an old family feud. When the truth comes out, she has to face unexpected enemies.
One interesting plot twist could be that their secret dating is discovered by a mutual enemy who tries to use it against them. Maybe the enemy spreads rumors in the demigod community, causing chaos and making Percy and Nico face some tough decisions about whether to come clean or keep hiding.
Some Tumblr blogs are also dedicated to Harry Potter fanfiction. You could search for tags like 'Ron and Hermione' and'secretly dating' on Tumblr. However, the content might be a bit more scattered compared to the big fanfiction platforms. But it's still worth a shot as you might discover some unique and well - written stories that haven't made it to the more mainstream sites yet.
