This variation on the second-chance romance obviously appeals for one of the same reasons that its more common cousin does: the idea that mistakes aren't forever, that forgiveness is not just a possibility, but a realizable promise. But it seems to be totally lacking when it comes to the second piece: familiarity. These pairs of lovers did not stay together long enough to really know much about the other, not in the same way that, say, Jane Austen's Anne Elliot and Frederick Wentworth (Persuasion) or Lisa Kleypas's Win and Kev (Seduce Me at Sunrise), Kristan Higgins' Harper and Nick (My One and Only) or even Sherry Thomas's Briony and Leo (Not Quite a Husband) do.
What different desires, then, do you think the one-night stand second-chance romance appeals to? What fantasies does it satisfy, that romances with longer-term first-chance stages don't?
