Cosmetic Playlover

Beauty consultant Natsume Mamiya is forced to work as a pair with Touma Sahashi, his junior. On top of everything, Touma — who has no respect for his work or for Natsume — has usurped his throne as the top seller!
One day, Touma finds out Natsume is gay and uses this to his advantage in a power-play, coercing Natsume to become his friend with benefits!
