A special class being held at a certain ● school. The lesson involves using actual mothers' bodies to study internal anatomy, instead of conventional mannequins—an astonishing educational method. Selected from numerous mothers, Kimika (53), driven by the desire to secure her son's academic future, resolves to offer her own body to the classroom. Suppressing her emotions like a mannequin, she exposes her most intimate areas in front of the students. Her figure represents a radical new approach to education, while simultaneously symbolizing the depth of motherhood and the spirit of sacrifice.
