Ignored and neglected by her own family, Cha Miso often escapes reality by immersing herself in her favorite novel, dreaming of living as the story’s beloved heroine surrounded by affection and happiness. But one day, that impossible fantasy suddenly becomes real when she awakens inside the novel itself.

Unfortunately, fate gives her the worst possible role.

Rather than becoming the cherished main character, she finds herself reincarnated as Eileen Etam, an overlooked side character destined to be abandoned and thrown out of her home. Determined to avoid repeating Eileen’s miserable future, she quietly begins planning her escape before disaster can strike.

However, her plans completely fall apart when Erno Etam—the infamous and unpredictable heir of House Etam—unexpectedly declares that Eileen is his daughter. Overnight, the once-forgotten side character becomes entangled in the dangerous power struggles surrounding one of the most influential families in the story.

Now trapped between noble conflicts, hidden schemes, and a growing cast of dangerous enemies, Eileen must navigate a future far more chaotic than the original novel ever suggested.
