It could mean many things. In Buffy fanfic, 'a mistake or fate' might refer to the characters' decisions. For example, Buffy's choice to be a slayer could be seen as both a mistake (because of the hardships it brings) and fate (as she was chosen). It could also be about relationships. Maybe a character's wrong decision in love was actually fate in disguise, leading them to their true love later on.
A twisted fate manhwa bl is appealing because it combines elements of fantasy, romance, and drama. The way the story unfolds keeps you hooked. Plus, the chemistry between the characters is just amazing.
One way it plays out is through character arcs. A character may start off believing their life is full of mistakes, but as the story progresses, they realize it was all leading to a fated destiny. For example, a side character who always felt like an outcast might discover that their unique abilities were fated to help Buffy in a crucial battle.
Well, strong character development is key. If the characters are well - rounded, with their own personalities, dreams, and flaws, it makes the love story more engaging. For example, in 'Call Me by Your Name', Elio is a complex character with his own insecurities and desires. Also, a good BL love story should have a believable relationship progression. It can't be too rushed. The story should give time for the characters to fall in love gradually, like in 'Given' where the relationship between Mafuyu and Ritsuka builds slowly as they get to know each other through music.
A beloved villain in a BL manga often has a complex personality. They might have a tragic backstory or hidden vulnerabilities that make readers sympathize with them despite their villainous actions.
Since I haven't read the 'rakked story', it's difficult to say precisely. However, if it's a story about relationships, perhaps Samantha makes the mistake of betraying a friend's trust. Maybe she spreads a secret that was told to her in confidence, which could lead to a breakdown in the friendship and other negative consequences in the story's world.
One thing that makes Supernatural French Mistake fanfiction unique is the blend of the Supernatural universe with a French - inspired setting. It's not something you see in the regular show all the time. The contrast between the dark, often American - based Supernatural world and the more 'exotic' (to the characters) French world creates a whole new dynamic.
The element of unexpectedness and the potential for character growth. It's the drama and the journey of the characters trying to make the best of an unplanned situation that draws people in.
