Ritsu is an alpha who hates alphas. "I want to bear a child," he says as he makes plans to change his sex through the "bitching" process before graduation. But his secret plan to turn into an Omega was found out by Yakumo, a unseemingly, normal F-rank boy. Yakumo presents him with an option to use him for his "bitching" plans. It turns out Yakumo is a lot more than he seems... Pairing with this strong alpha, will it help Ritsu realize his dream?!
