Aileen Lauren Dautriche's life changes forever on the day her engagement
with the crown prince Cedric Jeanne Elmir is nullified so he can be
together with Lilia Rainworth. The event triggers Aileen's memories from
her past life—she has been reincarnated in an otome game as the
villainess, who is destined to die in the final act. To prevent her
predetermined demise, Aileen has only one option: to court the game's
last boss, Claude Jeanne Elmir—the proclaimed "Demon King" and Cedric's
half-brother—and marry him.
However, it is easier said than done, as Claude distrusts her
intentions. Instead of giving up, Aileen adamantly tries to win his
heart by helping Claude fulfill his wish: to build peace between
humankind and demonic beasts. But time is running out, and it is up to
Aileen to change the course of not only her tragic ending but Claude's
as well.
