Mirume is a nineteen-year-old student at a small-town art school where Yuri, twenty years his senior, teaches lithography. Following chance meetings, they become enmeshed in a romantic liaison, and Mirume proves an eager learner under the tutelage of the free-spirited Yuri. But as his ardor warms, her feelings cool. Mirume finds comfort in the company of classmate En, who encourages his love affair even as she harbors a secret crush on him—and even as she herself is the unwitting object of the affections of Domoto, Mirume’s likewise tongue-tied best friend. When Yuri suddenly stops coming to school, Mirume is driven to seek her out at home, where he is startled to learn the realities of her life.
