Libido Effect

Graduate students Garib and Jinjoo, who are entomology majors, have been in a relationship for quite some time, dating since their freshman year. After living together for over three years, they start to experience boredom. One day, fearing that Garib might leave him, Jinjoo impulsively stings his finger with a mysterious insect known as Libidine, which has just appeared in the lab. To Garib's surprise, Jinjoo suddenly finds himself becoming aroused, even as Garib attempts to calm him by saying that nothing bad will happen. Intrigued by this unusual occurrence, Garib, who is deeply invested in their research, begins to exhibit a glow. Meanwhile, their advisor Coral and assistant Bada also discover Libidine's secret and decide to devise a plan to use it for their own intimate encounters.
