You woke up in the body of a villainous singer.

After reading her favorite book and watching the movie, a girl unexpectedly wakes up in the body of Velvet—one of the main villains of the story. According to the plot, Velvet and her twin brother Vesper were world-famous pop stars. Despite their talent and popularity, childhood insecurities made them doubt their own abilities, leading them to kidnap musically gifted trolls. Using a special diamond perfume bottle, the twins stole their musical essence to enhance their own voices. However, this process gradually killed the trolls.

The main protagonist of the story was Hunter—the son of an influential billionaire and politician, who once found himself turned into a troll. Living among trolls, he met Lilie, and together they experienced many adventures. When the heroes' friends were kidnapped by Velvet and Vesper, Hunter and Lilie set out to rescue them. Though they didn't succeed at first and their friends were on the brink of death, and they themselves were captured, they managed to escape, expose the twins, and free the prisoners. Velvet and Vesper were sent to prison, and Hunter, having briefly regained his human form, decided to become a troll again to stay by Lilie's side.

But now, everything has changed. The new Velvet is nothing like the old one. She is cheerful, confident, and kind to those around her. Moreover, she sings beautifully and has no intention of using others' voices for success. Knowing the future, the girl decides to change the fate of Velvet and Vesper, save their careers, and prevent the events that would lead them to prison. However, the more she alters the plot, the more she risks encountering the heroes prematurely and completely changing the story she once knew so well.
