[Funny, lighthearted story]
She transmigrated into the world of the Harry Potter books, and she was the wicked female antagonist... Not even a proper antagonist, just a minor character.
Though she knew the plot, she couldn't change it. As soon as she mentioned or did anything to stop it, she would be magically silenced and unable to move, and something unlucky would happen that very day.
But it was fine. The System said her mission was to follow the plot. She didn't have to worry about anything else, and once the story was over, she could enjoy a wonderful life. The only problem was that the System went missing!
After getting swindled, Pan Xi finally decided to be a cool, invisible slacker. That way, no one would notice her. She'd eat when it was time to eat, drink when it was time to drink, and treat following the plot like watching a movie. Life couldn't be more carefree.
What she didn't know was that the protagonists and all the other important characters in the book could hear her thoughts...
