Nostalgia — Tag Meaning
A mood tag for stories steeped in longing for the past — childhood summers, lost eras, or the early days of a relationship revisited through memory. It often structures fics around old photographs, returns to hometowns, or anniversaries that summon what was.
What to Expect From "Nostalgia" Fics
Expect wistful reflection, memory-laden settings, and bittersweet warmth rather than plot momentum.

Childhood Memories
Tags fic anchored in remembered childhood — flashback structures, nostalgia triggered by objects and places, or adults excavating who they were before everything happened. Authors use it to build backstory canon never supplied, with memory as the connective tissue between then and now.

Bittersweet
For fic that refuses to pick between joy and sorrow — reunions shadowed by what was lost, victories with a cost, love that arrived late. Authors reach for it when neither Fluff nor Angst is honest about the blend, and it often marks some of a fandom's most emotionally mature work.

Growing Old Together
The long-haul tag: a relationship followed into grey hair and shared decades, or glimpsed at its far end. For ships whose canons end in youth or tragedy, these fics are a quiet act of defiance — insisting the characters get the whole life, not just the dramatic part.

Introspection
Marks fic that lives inside a character's head — extended reflection on memories, choices, identity, and feelings, often with minimal external action. It is the natural home of quiet missing-scene fics where a character processes what canon rushed past.
