One common plot trope in Hermione and Severus cheating fanfiction is the 'forbidden love' aspect. Since they are from different generations and have different loyalties in the original story, their relationship in this type of fanfiction is often presented as something that goes against the norms of their world. Another trope could be the 'redemption arc' for Severus through his relationship with Hermione. Maybe he is shown to be a more sympathetic character as he engages in this relationship that is considered wrong in the eyes of others.
In these fanfictions, a frequent plot trope is the 'clandestine meetings'. Given that their relationship is supposed to be improper, they often meet in secret places. There's also the 'discovery and conflict' trope. When their relationship is discovered, it causes a stir among the other characters. It could lead to Hermione being ostracized by her friends or Severus facing more scorn from those who already dislike him. And sometimes, there's the 'change of heart' trope where characters like Hermione, who are initially against such a relationship, gradually fall for Severus.
Well, a common plot device is the 'tension - filled encounters'. Hermione and Severus might have unexpected and charged meetings where there is an instant attraction or connection that defies the normal expectations. Also, the 'power dynamic' can be a trope. Severus, being a teacher (initially) and Hermione a student, there's an unequal power dynamic that adds to the allure or the wrongness of their relationship in the fanfiction. And then there's the 'jealousy' trope. Other characters might be jealous of their relationship or try to break them up because they see it as a threat to the established order or their own relationships.
One popular trope is the 'enemies to lovers' where Severus initially dislikes Hermione but gradually falls for her. Another is the 'teacher - student relationship' dynamic which adds an element of forbidden love. And the 'redemption arc' for Severus through his relationship with Hermione is also common.
In the fan community, the idea of Hermione and Severus cheating fanfiction is a complex one in terms of ethics. On one hand, fanfiction allows for creative exploration of different relationships. However, it can be considered unethical by some as it goes against the original character dynamics in the source material. For Hermione, she is typically portrayed as a morally upright character, and Severus has his own complex relationships within the story. This kind of fanfiction might change the perception of these well - established characters in a way that some fans find unacceptable.
One common trope is the heroic rescue. Usually, her friends like Harry and Ron will come to her rescue in a daring adventure. Another is the 'damsel in distress' aspect, although Hermione is far from a typical damsel. Sometimes, the kidnapper might have some hidden motives related to her intelligence, like wanting to steal her knowledge.
In such fanfictions, a likely theme is self - discovery. Hermione's wealth could lead her on a journey of finding out more about herself, her capabilities, and her place in the wizarding society. Also, relationships are often a big theme. Her relationship with Severus could be explored in new ways due to her financial situation. For example, it might add an element of intrigue or conflict to their interactions.
I'm not entirely sure as I don't usually read this type of fanfiction. But I imagine one trope could be the miscommunication that leads to the cheating situation. Another might be the introduction of new characters that cause the relationship problems. However, the 'lemon' aspect might bring in tropes related to adult - like situations, which is not really in line with the original Percy Jackson which is more aimed at younger audiences.
One common trope is the love triangle. For example, a character might be in a relationship with one X - Man but then be attracted to or have an affair with another. It adds drama and conflict to the story.
In a 'werewolf claims Hermione' fanfiction, the transformation scenes of the werewolf are often a big part. It can be a moment of both danger and allure. Hermione might be the only one who can calm the werewolf during the transformation or she could be in danger during it. Additionally, the werewolf's pack dynamics can play a role. Sometimes the pack may not accept Hermione at first, leading to conflict and the need for the werewolf to fight for her acceptance within the pack.
One common trope is the 'enemies - to - lovers' arc. Since they start as enemies in the original series, fanfiction often takes this route. Another trope is the 'forced proximity'. Maybe they are locked in a room together in Hogwarts, which forces them to talk and understand each other. There's also the 'redemption' trope for Draco. He is often shown as trying to atone for his past actions and Hermione helps him in this journey, which in turn leads to their closer relationship.
One common trope is the 'enemies - to - lovers' dynamic. Since Draco and Hermione were initially at odds in the original series, in fanfiction, their flirting often starts as a form of sparring or challenging each other, which gradually turns into something more affectionate. For example, they might trade sarcastic remarks that slowly become flirty banter.
One common theme is the overcoming of differences. Since Severus is much older and has a rather dark past, while Hermione is young and full of idealism, stories often focus on how they bridge this gap. For example, in some fics, Hermione helps Severus come to terms with his past traumas.
