This story takes place at a school under the new educational system. It all began when a love letter addressed to Takeshi Kodama, the straightforward art teacher, from Yoko Kagawa, a young and beautiful female teacher, was found lying in the school hallway. It soon became clear that Ms. Kagawa was not the one who had written the letter, but this incident made her feel the need to explore the emotions of her adolescent female students.
