Help! I'm The Villainess In A Dating Game

The story

Robbed of her fiancé, ring, and life by her stepsister, Lucy wakes as Kaia Black, the doomed villainess in her favorite romantasy game. To survive, she must win four jewels from four irresistible knights—including seductive shadow wielder Zane. When her stepsister enters the game too, Lucy unleashes her power, claims the crown, and bets on Zane to win her revenge.
