[Machine Translation] The fifth grade three class of Hope Hill Elementary School, known as Ryota's class. Ryota Nakamichi, the homeroom teacher, may look modern with his brown hair and necklace, but he is 25 years old, tearful, straightforward, and willing to confront people with his whole self. Bullying, domestic violence, power harassment, juvenile crime... This is an unprecedentedly fresh coming-of-age novel that captures the "now" in the field of education through the figure of a young teacher who sincerely struggles to face the inevitable problems that occur inside and outside the classroom from the same perspective as the children.
