"Will you be a nude dessin model?" One day, a voice is heard from the art classroom of a male school. It seems that the drawing model is not able to come quickly and it is asking for the new art female teacher. If it is "for the student", it is shameful, and the clothes are taken off, a fresh woman is exposed. Boys and girls make fun of the mind. Today's class contents are spring paintings. The spring painting which depicts the sex and manners from the Edo period is taught in "practice".
