Alternate Universe - Hanahaki Disease — Tag Meaning
A universe where the fanon illness Hanahaki exists: unrequited love makes flowers grow in the sufferer's lungs, coughed up petal by petal until confession, requital, fatal bloom, or surgical removal that excises the love along with the roots. Originating in East Asian fanwork traditions, it has become AO3's most baroque metaphor for pining as literal disease.

Hanahaki Disease
The fanon illness itself, taggable in any setting: unrequited love manifests as flowers blooming in the lungs, progressing from stray petals to choking blooms, curable by requited feelings or by surgery that removes the love entirely. The surgical option is the genre's cruelest invention — survival at the cost of the feeling that caused it — and authors choose flower species for their meanings.

Unrequited Love
Love that is not returned — and a fic willing to sit in that ache. Some unrequited fics end in the feelings finally being answered, but the tag warns they may not; plenty of authors use it for the pure, unresolved hurt of loving someone who will never look back.

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.

Sickfic
A whole subgenre built on one premise: a character gets sick and someone takes care of them. Colds, flu, fevers, and stomach bugs are the classics, with the illness functioning as a trust exercise — the sick character must accept help, and the caretaker gets to show devotion through soup, blankets, and worry.
