Playing Daughter of the Duke’s Super Love Project as the easy mode heroine, Ivonne, makes charming the male characters a breeze. But once you switch to hard mode and step into the shoes of Penelope, the misunderstood villain, it’s nearly impossible to even stay alive! So imagine the shock of suddenly waking up in Penelope’s body―you know right away that your life is on the line. With love interests who will kill you if their affection meters drop too low and the inability to speak without choosing from pre-selected dialogue, it quickly becomes clear that Penelope’s chances have been rigged from the start―and this villain might just be destined to die!
