My classmate Rin Tomari and Kurumi. Draw the daily life of school life from the perspective of each of the three of them. Hajime, a childhood friend who likes Rin. Kurumi who makes him think is tempted by using a body. In fact, Rin, who liked Hajime, was made into a toy by his teacher Kozuka. Maria, the serious chairman, is an honor student who secretly thinks of Rin. And a good pet of my homeroom teacher Kozuka. A real-time school drama that mixes the feelings of each of the three.
