Kyomeikan Private High School has been deemed an "unprofitable business" by the company that runs it. Students score on the lower end of the national average range and are not particularly known to be strong in sports. With barely enough students to meet the minimum requirement to continue operating, Kyomeikan is a safety school for kids who didn't get in to their first and second choices.

One man is tasked with revitalizing the school's operations. Thirty-five-year-old Ryosuke Narumi (played by Sho Sakurai) is an elite corporate employee at Kashimatsu Bussan Co., Ltd., a large general trading company. He is suddenly assigned to the role of high school principal despite not having any experience as an educator. The realities of the academic world are so different from the rules in business that his days are filled with confusion.

"The job's too big for this young'un!" As expected, the teachers mock and resist Narumi. It's not as if they're passionate about the school's mission and values either. Mostly older and frustrated with their careers, the teachers have a jaded view of the educational system. Will Narumi succeed in turning Kyomeikan High School around? What lies ahead for him and the teachers?

This is not your typical academic drama that depicts the friendship and love between students and teachers. It's a human drama about the lives of the professionals who educate our children.
