Born into a martial arts family, her father is a highly renowned expert in the eyes of insiders, and her mother is a beautiful woman with charm that can captivate many even as she approaches forty. Don't assume that children growing up in such a family are without worries. Under the lively gazes of outsiders, Xiaoxi (played by Shim Min-Ah) often feels a sense of loss. In order to follow the ancestral instructions and achieve the revival of the Central Plains martial arts world, she has been more mature than other partners since childhood, bearing a difficult mission. This also makes many joys vanish into thin air. Ying (played by Moon Ju-Wan), who practices martial arts with Xiaoxi since childhood, gradually develops admiration for her. In the eyes of both sets of parents, they are a perfect match and maintain an intimate friendship.
New students often become objects of teasing and pranks by senior students, and Xiaoxi was no exception to this "traditional rule." However, due to her excellent skills, she quickly subdued all the experts in the university's sports department, and the transfer students temporarily submitted to her.
By chance, Xiaoxi meets Junmao (played by Liu Jian), the skating prince of the famous school "Huacong," and falls in love at first sight. In front of the boy she likes, she has the idea of giving up being a hero for the first time in her life. For Xiaoxi, who has always been fearless and accustomed to being a "tomboy," showing gentleness and dependence like a lady in front of Junmao is the top priority. To get closer to Junmao and make him her subject, she starts paying attention to her appearance and demeanor training, joins the skating club she hates the most, and even quarrels with her parents and runs away from home. Unfortunately, the coach assigns her to the "loneliest position" — the goalkeeper. Even more difficult to deal with is that the previous experts, seeking revenge, try every means to reveal Xiaoxi's true "barbaric and rude" nature in front of Junmao; while Ying, who has always regarded him as a good friend, also launches a romantic pursuit towards her. Before she can sort out these messy issues, the legendary family enemy sends a declaration of war. Can Xiaoxi defend the righteous martial arts world and find her true love?
