One moment, she’s about to inherit an enormous fortune. The next, she wakes up trapped inside a chaotic wealthy-family drama novel—and not as the beloved heroine, but as the infamous villainess doomed to a miserable ending. Worse still, she has already framed the story’s heroine and treated the future main villain like nothing more than a convenient blood source, successfully making enemies out of nearly everyone around her.

In other words, her situation is a complete disaster.

Knowing exactly how horribly the original story ends for her character, she immediately realizes there’s only one way to survive: change everything before it’s too late. That means abandoning her arrogant and manipulative behavior, repairing her relationship with the heroine, and desperately trying to appease the terrifying villain she previously abused.

Thus begins her hilarious and chaotic transformation from spoiled troublemaker to obedient little sister figure, all while navigating dangerous family politics, emotional misunderstandings, and the constant fear of triggering her own tragic ending.

Because in this twisted world, one wrong move could still get her destroyed at any moment.
