"Today it's my turn to throw a punch! I will swing towards this world with all my strength!" Xiaen (played by Du Zhiyuan) is a gentle and virtuous housewife. Her daughter, Lingqiao, who is in junior high school, is clever and sensible. Her husband, Zhu Chang (played by Park Sang-uk), is a well-known professional boxer. For the past 13 years of their marriage, she has been silently supporting her husband's career, with her own struggles that she cannot express in front of others. Perhaps due to the nature of his profession, whenever there is a disagreement between the couple, her husband resorts to using his fists on Xiaen, just like in the boxing ring. One day, Xiaen unintentionally witnesses her first love being beaten to death by her husband in the ring. With her kind heart, she ignites a fighting spirit and finally decides not to endure silently anymore. She is determined to learn boxing from scratch and challenge her husband. Lost and in search of a boxing coach, Xiaen coincidentally meets Juxuan (played by Sun Xianzhu), a retired boxer who seems quite eccentric. With his sponsorship, Xiaen secretly practices boxing behind her husband and family's backs. She goes to her husband's matches to observe and study his weak points. As the day of the match draws closer, what will happen when her arrogant husband discovers that his final opponent is none other than Xiaen, who is usually frail and weak?"Alright, let's duel in the ring!" Xiaen openly declares war, making headlines in major media outlets. Will she be able to regain her dignity and achieve success in this match?
