A debt-ridden extra from an R-rated reverse harem novel is just trying to survive when the story’s heroine suddenly dies, taking her last hope with her. Then the heroine’s family asks her, a commoner, to pose as a noble lady and keep a family engagement intact, offering enough money to erase all her debts. She agrees, thinking it will be a simple job before she leaves—but after one small act of kindness toward the heroine’s pitiful fiancé, the once gentle man begins to change into a bold and dangerously seductive pursuer who is determined to make her fall in love with him.
