Synopsis

Ciela Labyrinthe is a minor character in the novel she's been dropped into — one whose story ends at the guillotine. Determined to rewrite that ending, she has been quietly nudging the plot in a safer direction. She just didn't expect it to go quite this sideways. When the heroine cheerfully announces she's fallen in love with Ciela's own fiancé and asks if they can still be friends, Ciela realizes the story has gone completely off the rails — the heroine was supposed to end up with the crown prince, not steal her betrothed. Fine. If her fiancé is a write-off, maybe it's time to trade up. In a fit of reckless spite, she dashes off a letter to the crown prince proposing that two people who've both been left out in the cold might as well keep each other company. Shockingly, he says yes. A revenge romance full of unexpected sincerity begins.
