"Parfum Magic" is a magical apothecary run by Leila, a witch capable of reading magical power through scent. While outwardly operating as an ordinary shop, the various aphrodisiacs she brews in the back have quietly gained popularity among noblewomen troubled by matters of the heart. One day, Dion, the commander of the Order of Knights, visits Leila’s shop to investigate illegal magical potions; amidst the ensuing commotion, he is accidentally exposed to one of her aphrodisiacs. His reason begins to waver as the potion, which should have had no effect on him, triggers a memory linked to a "nostalgic scent." This encounter, guided by fragrance, eventually sets their destinies on a new path.
