Break Up — Tag Meaning
Tags a breakup occurring in the fic, with no promise of repair attached. Some break-up fics are the first chapter of a reunion; others are autopsies — examinations of how a relationship ended, written for catharsis rather than comfort. The surrounding tags reveal which you're holding.
What to Expect From "Break Up" Fics
The end of a relationship rendered on-page, with the aftermath as the story. Bring expectations calibrated by the ending tags.

Breaking Up & Making Up
The canonical tag for the full cycle: the relationship ruptures and repairs within the same story. Authors use it to put a couple through a real crisis — not a misunderstanding but an actual breakup — and then do the harder work of writing a credible way back.

Exes
Flags a past romantic relationship between characters as live story material — the history hangs over every scene, whether they're working a case together, attending the same wedding, or pointedly not talking. The tag doesn't promise reunion; sometimes the point is the wreckage.

Angst
One of the foundational tags of fanfiction, covering stories centered on emotional pain — grief, longing, guilt, heartbreak, despair. Unlike a content warning, Angst describes mood: the fic dwells in difficult feelings and wants you to feel them too. It says nothing on its own about whether things improve.

Sad Ending
The honest counterpart to Happy Ending: this story concludes in loss, separation, or grief, and the author is telling you up front. Tagging it is considered basic courtesy on AO3, since an unmarked sad ending is one of fandom's cardinal reading betrayals.
