The girl is secretly in love with the tall and handsome Tsukino-sensei, who meets all her requirements for an "ideal man". However, there is an old perverted teacher, Tamura-san, working at the academy, who chose Shiina Chizuru-chan as his sexual target. Tamura-sensei devised a whole plan that will give him the necessary advantage. He plants money from the academy's "common fund" into Tsukino-sensei's personal belongings, making him a thief and scoundrel, and a little later reveals this "terrible secret" to Chizuru-chan. The girl is ready to do anything to protect and save the honor of her beloved. Tamura-sensei, with the help of a small trick and blackmail, completely enslaves the mind and body of the stubborn chaste anime beauty.
