Past Relationship(s) — Tag Meaning
The canonical tag noting that prior romances exist in the story's background and matter — an ex who shaped a character, baggage carried into the current pairing, history that surfaces at inconvenient times. It manages expectations: the current ship isn't anyone's first love.

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.

Second Chances
The hope-shaped tag: someone gets another shot — at a relationship, at making things right, at a life that went sideways. Broader than exes-to-lovers, it covers redemption-tinged romance, reconciled friendships, and time-loop do-overs alike, unified by the belief that it's not too late.

Jealousy
The green-eyed catalyst: a rival's attention, an ex's return, or a stranger's flirting forces a character to confront feelings they'd been ignoring. In fanfic jealousy is most often the device that breaks denial — nothing clarifies wanting someone like watching someone else want them.

Minor or Background Relationship(s)
A courtesy tag indicating that ships beyond the main pairing exist in the fic but stay peripheral — mentioned, glimpsed, not explored. Authors use it so readers filtering for those side pairings aren't misled into expecting real content for them.
