A quiet office worker dies after enduring workplace bullying and awakens inside the fantasy novel she adored. Rather than becoming the heroine, she finds herself reincarnated as Lucia, the feared "Ice Villainess"—the very woman hated by her favorite character, Prince Albert. Lucia knows the novel's future all too well: after their political marriage, Albert is supposed to fall in love with the Saintess, leaving Lucia abandoned. Instead of accepting her tragic fate, she decides to rewrite the story. Armed with her knowledge of the original plot and her unwavering love for her favorite character, Lucia tries to win Albert's heart while avoiding the disastrous ending that awaits her. Blending comedy, romance, and villainess tropes, the series follows Lucia's efforts to change destiny and prove that even a so-called villainess deserves a happy ending.
