When Park Eunha dies in modern-day Korea, she awakens in the body of Raeliana McMillan, the eldest daughter of a nouveaux riche baron. However, this is no ordinary world; it's the exact same one as a novel she once read. Beloved by her family, it would seem as though she is in a fairy tale. But Raeliana is far from the main character—she is a mere plot device, whose murder at the hands of her fiancé instigates the entire story. 

Raeliana has no intention to accept her fate quietly. She sets her eyes on someone in a position of great power—the vieux riche male protagonist Duke Noah Volstaire Wynknight—aiming to completely change the original story. Using her knowledge of future events, Raeliana offers information to Noah on the condition that he acts as her fake fiancé, but the Duke's two-faced nature throws a wrench in her plans!

Nobody understands why the brilliant six-year-old Inés Valeztena de Perez picked Cárcel Escalante de Esposa as her fiancé. Considering her family's high status, she could have easily married the crown prince and led an outstanding life as the empress. Cárcel grew up believing that Inés loved him deeply, despite her eerily emotionless demeanor and understated style. But, put in a difficult position against his will, he harbored no affection for such a dull person and instead turned to countless other women behind her back.

Cárcel's whole reality crumbles when Inés catches him in the act—because she does not care whatsoever. She intends to turn a blind eye to his infidelity even after tying the knot, which leaves Cárcel in complete disbelief. Inés' indifference ignites a perverse desire inside Cárcel, and he abruptly loses interest in everyone else. However, there is a reason behind each of Inés' actions, and it all started when she took her own life for the very first time.
