The story is based on a Chinese web comic and follows Shi Miao, a high school student who despises her elder brother, Shi Fen, due to his laziness, incompetence, and unreliability. Despite relying on one another, their constant fighting arises from Shi Miao's violent tendencies and Shi Fen's penchant for stirring up trouble. Although Shi Fen cares for his younger sister, Shi Miao hopes to be rid of him. The series aired earlier in China than in Japan.
