In a Scent

Seo Lee-jun, an obscure actor, ends up substituting as a guest-for-hire at an engagement ceremony upon an acquaintance's request. However, he is thrown into panic upon realizing that the groom-to-be is Cha Jae-hyun...a top star actor and the very man he accidentally spent a night with a few days prior. Lee-jun comes to share a secret with Jae-hyun, an Omega living as an Alpha while keeping his pheromones perfectly concealed. This unexpected reunion begins to steer the relationship between the two in a whole new direction... "How on earth are you able to sense my pheromones? The night is long, so take your time and tell me."
