Yun-yeong decides to learn Jiu-jitsu, feeling sick of herself. Despite all her efforts, it is difficult to stop hating herself, continuing to think she is weak because she is a “woman.” To accept her femininity as it is, she visits Lee Hee-jin, the one and only Korean woman who is a Jiu-jitsu black belt holder. Hee-jin explains about what kind of strengths a woman practitioner can have and how Yun-yeong’s weakness can become her strength. Deeply touched by Hee-jin’s words, Yun-yeong pulls herself together to fight at a Jiu-jitsu tournament and realizes she must fight to overcome her strength and weakness and it is important to accept herself for who she is. Yun-yeong continues to learn how to fight and becomes more like a “women.”
