Wails of the Bound: Volume 1 -- Keri Kusabi, Paperback

Alpha Keisuke Takaba has just transferred to a new office, hoping for a peaceful work environment filled with fellow Alphas. His illusions are quickly shattered when he meets his new manager, Miyabi Karasuma--a brash Omega who is willing to use his body to get whatever he wants. Keisuke can't stand Omegas, but no matter how hard he tries, he can't avoid Miyabi and is even forced to follow along as Miyabi performs "favors" for business associates. The more he sees of Miyabi's life, the more he feels pity for the Omega... but maybe "pity" isn't the only thing he's feeling?
