After accidentally falling, she actually finds herself bound to a Second Female Lead Counter Attacking System!

Beatrice Da Ville was supposed to be the villainess. A spoiled, arrogant noblewoman who terrorized the heroine, only to be executed for her crimes. At least, that’s how the story was supposed to go.But when a 21st-century woman wakes up in Beatrice’s body, she has zero intention of following the original plot. Execution? Betrayal? A bloody downfall? Absolutely not. She just wants to keep her head down, avoid drama, and live a long, peaceful life.Unfortunately, her unbothered attitude, modern slang, and sheer survival instincts keep catching the attention of all the wrong people. The nobles think she’s a genius, the royal family is amused, and worst of all—the cold Crown Prince Francois Montague, who was supposed to fall for the heroine, won’t stop watching her.Meanwhile, the original heroine, Johanna Lockhart, starts to realize that her perfect fairytale is slipping away. The world that once adored her now whispers about Beatrice instead. And the more she loses, the more dangerous she becomes.With a fate that refuses to let her go, a jealous heroine turning villainous, and an infuriatingly handsome prince who definitely didn’t love her in the original story, Beatrice has one goal.Survive. Thrive. And absolutely, under no circumstances, follow the script.
