Lucia, a girl born into a struggling baron family, has relied on the financial support of her childhood benefactor Rosalinde just to keep her household afloat. Thanks to Rosalinde's patronage, Lucia gains admission to an elite academy for the wealthy. Almost immediately upon arrival, however, she is caught up in Rosalinde's chaotic romantic schemes. Rosalinde is a self-proclaimed "villainess" with memories of a past life as an otome game player, and she is convinced that the story she is living in follows that same game script. She believes she must play the antagonist and that Lucia, as the destined heroine, is supposed to steal the crown prince away from her. The complication is that Rosalinde is clearly in love with Crown Prince Reinhardt, and he is just as clearly and openly devoted to her. To humor Rosalinde's delusions and move his own romance forward, the prince asks Lucia to act as a decoy and pretend to pursue him. Frustrated by this farce but bound by gratitude, Lucia reluctantly agrees to play the designated heroine role. As she maneuvers through Rosalinde's increasingly elaborate villainess performances and the prince's sly countermoves, she crosses paths with Dill, a quiet and steadfast young man who watches her from the sidelines and waits for her with genuine patience. The story unfolds as a romantic comedy set within the academy, where misunderstandings, staged love triangles, and the antics of a fandom-fueled self-proclaimed villainess draw Lucia deeper into a tangle of schemes. Through it all, Lucia remains a pragmatic and resilient protagonist who quietly works toward her own goal of securing a dependable husband and a stable future, turning a farcical situation into an unexpected path toward her own happiness.
