Cheyukgyosa Kim Gye-Ran

Kim Gye-Ran is a physical education teacher whose conviction is straightforward: nearly any problem can be addressed through exercise. She is assigned as the homeroom teacher for the third-year Class 3 at Muscle High School, a placement that puts her enthusiasm in direct contact with students and their varied concerns. Rather than approaching their issues through conversation or conventional counseling, her instinctive response is to propose a run as the starting point for any discussion. The premise follows how this single-minded philosophy intersects with the daily realities of the classroom she has been given charge of.
