Age Difference — Tag Meaning
Flags a notable age gap between romantic partners — both adults, with the gap itself a live element: differing life stages, others' judgment, or the characters' own hesitation. Authors tag it for transparency, since the dynamic is sought by some readers and avoided by others.
What to Expect From "Age Difference" Fics
An adult relationship where the age gap is acknowledged and negotiated rather than ignored. The maturity contrast often shapes the dynamic's appeal.

Slow Burn
The tag that warns — or promises — that the central relationship will take a very long time to arrive. Slow burn is a craft commitment: tension built across tens of thousands of words, feelings denied and deferred, every near-moment interrupted. Its devotees consider the wait the entire point.
