Do Yeon majored in Social Physical Education in college and dreams of becoming an action star but only gets minor roles. His long-time girlfriend dumps him and nothing goes well as he plans. But, a chance comes to him. An after school class teaching position. He becomes a teacher because of his teacher getting him mixed up with another student. It's an opportunity for him and also a crisis.
Maybe he could do it well with his father's advice and his brother's help. And there are only six students enrolled for class. But he thought wrong. The six students were those who the school almost gave up on. They ignore Do Yeon and he doesn't know what to do. But, there's always a way out. His specialty is getting hit well. Dodging when a punch comes at him and knowing how to get punched with or without feeling pain. Don't you want to know what changes he will make?
