Miscommunication often plays a big part. The characters may not be able to express their true feelings or may misinterpret each other's actions. This can cause a lot of unnecessary drama and make the relationship seem 'bad'. Like in a story where one character thinks the other is uninterested when in fact they're just shy.
Power imbalance is a common theme. One character may have more control or influence over the other, leading to a tumultuous relationship. For example, in some novels, one character might be wealthy and use that to manipulate the other.
Obsession is also a big theme. The 'bad love' aspect can be shown through one character being overly obsessed with the other. This can lead to possessive behavior. In a mafia setting, this can be even more extreme as the characters are used to getting what they want. For instance, a mafia boss might be obsessed with a younger man and use his power to keep him close, even if it's not healthy for the relationship.
One common theme is probably the idea of unexpected love. The 'idiot' in the title might suggest that the character is not the typical ideal partner at first glance, but love still blossoms.
Love and acceptance are common themes. The story often shows how the two male characters, one being a dragon or having a connection to dragons, overcome social or species - related barriers to be together.
Love and self - discovery are common themes. The characters often find themselves while falling in love with another man.
One common theme is the idea of taming the wild. The 'big bad wolf' character is often seen as untamed and the heroine is the one who manages to soften him. For example, in many novels, the wolf - like hero is rough around the edges at the start but through his love for the heroine, he becomes more civilized.
The theme of forbidden love often appears. Since it's BL, in a horror context, the love between the two male characters might be seen as something that goes against the norm in the spooky world they are in. Maybe there are forces trying to keep them apart because of their relationship, which adds an extra layer of drama and horror to the story.
Power dynamics also play a role. There could be a dominant and a submissive character, which adds an extra layer of tension and excitement to the relationship. This can be seen in novels where one character is in a position of authority, like a CEO or a senior in a school, and the other is more inexperienced.
Self - discovery is also a prevalent theme. The characters in the fanfic may be on a journey to understand their own feelings and identities, especially when it comes to their sexual orientation in the context of a BL relationship. And of course, there's the theme of unconditional love. Despite all the obstacles they might face, the love between the characters remains strong.
One common theme is self - discovery. The transmigrating character often has to figure out who they are in a new world and how they fit in. For example, they might discover new abilities or aspects of their personality. Another theme is the changing of fate. They try to change the original plot, especially when it comes to the fate of the male love interest.
Love and relationship are the most common. These stories often explore how two male characters fall in love, face challenges in their relationship like social acceptance or family opposition. For example, in 'Given', the characters have to deal with the loss of a loved one while also navigating their new - found feelings for each other.
