I think 'after quotes fanfic' might be fanfiction that is written with a focus on what happens after a significant quote in the source material. Say in a popular anime, there's a powerful quote said by the main character during a battle. A fan might write a fanfic that explores the events, emotions, and character development that occur after that quote was spoken. It's a way for fans to expand on the original story in their own creative way.
Not necessarily. Quotes are often used to add emphasis or convey direct speech, but not all fiction requires them. It depends on the style and the story being told.
Maybe 'In an all - or - nothing marriage, commitment is the unwavering thread that holds everything together.' This shows that in such a marriage concept, commitment is of utmost importance. It's like the backbone that supports the relationship through all its ups and downs.
