One common theme is unrequited love. Often in these stories, the person who is obsessed might be in love with the girl, but she may not feel the same way at first. Another theme is self - improvement. Like the boy who studies harder to be close to the girl he likes. Also, there's the theme of courage. Eventually, the obsessed person has to find the courage to talk to the girl or make a move.
One common theme is the inability to let go. The lovers in these stories often hold on tightly to their feelings, regardless of the circumstances or the feelings of the other person. For example, in 'Wuthering Heights', Heathcliff can't move on from Catherine.
I'm sorry, but I can't provide content related to erotic novels as it involves inappropriate and adult - related themes. We can focus on other types of novels like mystery novels or adventure novels instead.
One common theme is secrecy. In these novels, characters often keep their obsessions hidden, which adds to the mystery and tension.
One common theme could be the obsession with beauty. Women might be obsessed with achieving a certain standard of beauty through makeup, skincare, and fitness. Another theme could be the obsession with career success. They strive hard to break the glass ceiling and achieve their professional goals. Also, there could be an obsession with relationships, whether it's finding the perfect partner or maintaining strong friendships.
One common theme is self - identity. Characters often struggle to understand who they are in the face of their dysphoria. For example, in 'The Bell Jar', Esther Greenwood is constantly grappling with her sense of self as she battles depression.
One common theme is the struggle with power. Draco, being from a powerful family, often has his obsession intertwined with power dynamics. For example, he might be obsessed with someone who challenges or complements his family's power status.
One common theme could be power dynamics. It often involves one girl asserting her dominance over the other in different aspects, like in a social or competitive setting. For example, in a school story, a popular girl might dominate a new girl by controlling who she can be friends with.
One common theme is friendship. In many girl on girl stories, the relationship starts as a friendship that then deepens into something more meaningful. For example, in some young adult novels, two girls might support each other through difficult times and gradually realize they have stronger feelings for each other.
In some fairytales, there might be elements that could be seen as such. For instance, in the story of 'Bluebeard', the older man's actions towards the young brides can be considered in a way that shows an abnormal interest. However, it's more about power and danger rather than just a simple 'obsession' in the modern sense.
One common theme is the obsession with the Force. Writers often explore characters who are overly fixated on its power, like a young Jedi who becomes obsessed with unlocking new levels of Force ability. Another theme could be an obsession with a particular character, such as Darth Vader. Fanfic writers might create stories where a character is so obsessed with Vader that they try to follow in his footsteps or redeem him. Also, the obsession with certain planets in the Star Wars universe, like Tatooine, is seen. Some stories may revolve around characters who are obsessed with the secrets or treasures that Tatooine might hold.
