Class 2-C is a rough place. The students abuse their homeroom teacher, Miss Ogino, and made doing so their favorite pastime activity. Even in her hopelessness, Miss Ogino has a routine: She writes letters to the students who are not attending school. In them, she writes that her class is wonderful and full of hope. Only in these letters could Miss Ogino be an “ideal teacher”. One day though, Yoarashi, a student to which Miss Ogino was sending letters, showed up at school. She tells Ogino that she is worried that her lie will be exposed. This is where their "education" began.
