Cheong-ho, a national swim team member and alpha, has been having a hard time breaking his poor records. He believes that engaging in sexual activity with an omega could do wonders for his physical abilities, but his fear of their pheromones is holding him back. That is, until he meets Yi-rim, an omega who doesn't emit any scent. Yi-rim eagerly helps Cheong-ho, and they start a purely physical relationship that seems too good to be true. Though they seem like a perfect match, they struggle to truly form a connection.
