Obsession — Tag Meaning
The broader fixation tag, covering romantic obsession, a villain's preoccupation with a hero, or a rivalry that consumes someone's life. It signals intensity that has stopped being healthy, and fandom uses it for both psychological character studies and deliberately dark ship dynamics.
What to Expect From "Obsession" Fics
A consuming fixation as the story's engine. May be romantic, antagonistic, or both at once — the ambiguity is often the appeal.

Yandere
From Japanese fan vocabulary: a character whose sweet, devoted exterior conceals violent, possessive obsession with their beloved. Yandere fic is openly a dark fantasy genre — love as captivity, devotion as threat — and the tag is a clear flag that the romance depicted is intentionally unhealthy.

Enemies to Lovers
Perhaps the most famous relationship arc in fanfiction: two characters who genuinely oppose each other — rivals, adversaries, people on opposite sides of a war — fall in love. The appeal is the transformation itself: hostility's intensity rerouted into intimacy, with all that built-up attention finally changing valence.

Dark
A tonal warning that the fic ventures into bleak, disturbing, or morally ugly territory beyond what its fandom usually entertains. It frequently modifies a character ('dark' versions of heroes) or an entire premise, and conscientious authors pair it with specific warnings about what makes it dark.
