Second Chance

They loved each other once, it ended, and the story picks up where the regret lives. The trope carries freight no meet-cute can: shared history arrives pre-installed, and every present-day scene plays against a ghost version the reader assembles from flashback and inference.

The promise is the genre's most adult one, that timing can be forgiven, that the person you became can succeed where the person you were failed. Which makes the craft requirement non-negotiable: the original ending must have been legitimate. If the first breakup was a misunderstanding, the reunion is bookkeeping; if it was two real people failing in ways that made sense, the second attempt has something to prove and a reason to fear. The desk's test is whether both leads changed in the interval, visibly and relevantly. The common failure is a decade of separation that altered nobody, which suggests the years were scenery and the second chance is just the first one, resumed.
