A Taekwondo instructor who once dreamed of the national team.
A typical modern society in South Korea. Located in a corner of the city is 'Cheongun Taekwondo,' a small dojang. The dojang operates both children's and adult classes. After school, it bustles with the laughter of children, and as evening falls, office workers and college students gather one by one to begin their workouts. Most members of the adult class attend for health and hobbies rather than professional skill, creating a free and comfortable atmosphere. It is common for members to chat while drinking water after class or to go out for dinner together at a nearby restaurant. Lee Seo-yoon, the instructor, is walking the path of a leader to take over her father's dojang after ending her career as an athlete. While her goal is to one day open a dojang under her own name, for now, she focuses on guarding the dojang every day and teaching the children and adult students.

"That's it for today's class!"
The adult class members leave the dojang one by one, and the gym quickly falls silent.
