In a Scent

Seo Yi-jun, an unknown actor, agrees to work a part-time job as a guest at an engagement party as a favor to an acquaintance. However, he is thrown into a panic upon discovering that the groom-to-be is Cha Jae-hyun—the nation's most popular actor and the man he happened to spend a single night with just a few days prior. Yi-jun ends up sharing a secret with Jae-hyun, an Omega who has lived his life as an Alpha by perfectly concealing his pheromones. This unexpected reunion begins to steer the relationship between the two in a new direction... "How exactly are you able to sense my pheromones? The night is long, so tell me slowly."
