Cheong-ho is a national swim team member who has been struggling with poor records. As an alpha, his physical condition could be improved greatly through sex with an omega, but he has a fear of omega pheromones. His hopes of being a top swimmer seem to be sinking, but that all changes when he meets Yi-rim, an omega whose pheromones don’t give off any scent. Yi-rim is only too happy to help Cheong-ho out, and thus the two of them start a purely physical relationship. It’s almost like they’re a match made in heaven. But...why is it so hard for them to close the distance between each other?
