Set in a medieval setting, this story takes place in an orc ABO universe. Flora’s older sister was tortured to death by Odette, the Beast King’s fiancée, out of jealousy because her pheromones showed a 99 percent compatibility with the Beast King—a fact the Beast King himself condoned. Flora is determined to avenge her sister but finds no one to turn to. In her despair, she encounters the Beast King’s biological sister—a woman who had once shared hardships with him as they grew up together, only to eventually be reduced to a mere pawn in his power struggles and left virtually incapacitated. The two women, united by a shared hatred, decided to join forces. After undergoing a series of transformations at the hands of the Beast King’s sister, Flora became a woman whose pheromones were 100 percent compatible with the Beast King’s. She was trained to cater to his desires, approached the Beast King, and began her revenge amid a tense, ambiguous tug-of-war with him.
