When one woman is afflicted with a disease that causes her to go into heat, she winds up in the world of sex-espionage and paired with a handsome, experienced man!

Jun never imagined her life would lead to being recruited by a secret intelligence agency specializing in sex espionage. Her unusual condition, "excessive pheromones," makes her a natural at seduction, but it comes with a price: uncontrollable bursts of heat that make her a danger to herself and those around her. Fired from her job and desperate for a new start, she reluctantly accepts the agency's offer to become a honey trap operative.

To train Jun in the art of seduction, the agency pairs her with Issui, a cool and enigmatic veteran. Issui takes a hands-on approach, guiding Jun through intimate lessons that leave her flustered and craving more. But just when she’s ready to surrender to the pleasure he offers, Issui’s own hidden struggles hold him back.

Their partnership is supposed to be strictly professional. Can they keep their desires in check, or will their undercover work lead to something far more personal?
