Shoehua (played by Wang Xinling) is a freshman girl student who is good at judo and playing musical instruments. She is pure and lovely. In the family of six siblings of the Tianzhong family, she ranks the youngest, and is the only girl in the Tianzhong family. Shoehua falls in love with Shirou (played by Wang Dongcheng), a student from Tama First Senior High School. Shirou has an introverted personality, excels academically, and is also skilled in judo. Regarding their sister's first love, Shoehua's four brothers, who have a super younger sister complex (played by Zhu Xiaotian & Fashion F3), constantly obstruct the romance between the two. Shoehua's fifth brother (played by Huang Jinglun) is responsible for keeping an eye on her at school. As a result, he was forced to give up his top choice university and instead attend Tama Senior High School. Tongzi (played by Li Jiaying), Shirou's childhood friend, wants to take Shirou away; while the judo club president (played by Chen Yiru), who fell in love with Shoehua at first sight, starts pursuing her. Despite all these obstacles, Shoehua still goes all out to pursue her romance with Shirou...
