In the studio of the morning childrens' show Together with Mama, a crew of miserable adults prepares their facades of amicable smiles and cheerful exteriors to educate a group of innocent preschoolers. In the middle of it stands Uramichi Omota, a former gymnast who can't help but bring the kids down to earth by revealing the harsh and depressing reality of adulthood, even in front of the rolling cameras. Behind the scenes, Uramichi's much-desired peace is disturbed by his two bothersome juniors who work as the show's rabbit and bear mascots and singers: Utano Tadano, a woman who only wishes to get married; and Iketeru Daga, a handsome man with a crass sense of humor. From smoking and exercising to nihilistic outbursts, everyone's big brother Uramichi always brings up the not-so-moral side to his life lessons.

Kei Kunieda is a newscaster who strictly maintains an amiable and kind persona while at work. Although he smiles on the outside, he covertly curses at others to his heart's content. His everyday life is smooth, even if he keeps half of himself hidden at all times, but that changes when he meets Ushio Tsuzuki, an independent stop-motion animator. Soon, Kei finds himself caught in a lie borne from his two personas meeting Ushio under different conditions, with the other man unaware they are the very same person. As feelings begin to blossom between them, Kei cannot be sure if Ushio will love both sides of him—or only just half.
