"Parfum Magic" is a magic apothecary run by Leila, a witch who can read magic power through scents. While operating as an ordinary pharmacy on the surface, the various potent aphrodisiacs prepared in the back of the shop have secretly gained popularity among ladies troubled by love. One day, Dion, the Captain of the Knight Order, visits Leila's shop to investigate illegal magical drugs and, in the midst of a commotion, ends up doused in an aphrodisiac. A "nostalgic scent" combines with the drug that shouldn't have worked on him, causing his rationality to waver. This encounter, led by a fragrance, will eventually change their fates——.
