“Who else would teach you about love if not me?” Dr. Jonathan is a prickly genius who cares about nothing but research. He’s just made an astonishing invention that could change humanity’s mating dynamics: the “love potion,” a.k.a. the “pheromone cocktail”! Thrilled at the thought of getting rich, Jonathan orders his TA, Sabrina, to arrange a press conference. Sabrina asks to have her name mentioned as a co-researcher, but Jonathan coldly refuses. Enraged, Sabrina charges at him, and after a fierce scuffle the pheromone cocktail splashes over them both. Intoxicated by the cocktail, Sabrina begins seducing Jonathan and snaps handcuffs on him, tying him up so he can’t attend the press conference. Four hours remain until showtime… Can Jonathan satisfy Sabrina in time?

By his side since childhood is beta So Gi-hyeon, who has quietly watched over him for years while nurturing his love alone. What once seemed like an unbreakable relationship begins to crack the moment Gi-hyeon confesses.

Faced with such cruel, bone deep rejection, Gi-hyeon tries to quietly bury his feelings, but Yeon-oh refuses even that. Driven by selfish obsession and a need for control over what he considers his, Jo Yeon-oh will not allow Gi-hyeon to leave his side. *“Fine. Let’s date. You selfish bastard.”* Instead of cutting ties, what begins is a deceitful relationship. Yet because it is Yeon-oh’s choice, Gi-hyeon accepts it without protest. *“If you really can’t stand it, I said I’d help you find someone. Stick to omegas if you can.”* Even while they are dating, Yeon-oh coldly suggests that Gi-hyeon sleep with others, a twisted form of consideration that steadily carves wounds into Gi-hyeon’s heart. Eventually, Gi-hyeon reaches his limit. And at the end of his long, desperate unrequited love, Gi-hyeon is confronted with a physical change he believed could never happen.
