The Shi siblings have a lot on their plates, such as needing to stay frugal, passing their exams, and constantly dealing with each others' antics. Older brother Fen's frivolous demeanor often gets on his younger sister Miao's nerves, leading to physical but comedic altercations. Fortunately, their friends are always around to offer a helping hand. Kai Xin is Fen's well-meaning best friend who rivals Fen's absentmindedness but makes up for it with his athleticism. Miao, on the other hand, is often accompanied by her bubbly companion Miaomiao. The most recent addition to the group is Wan Sui, who is desperate to conceal his wealth but remains tirelessly loyal to his peers—sometimes roping his younger brother Xing into their excursions. Sometimes, the friends' roundabout means of problem-solving backfire. However, no predicament is going to prevent them from discovering how fun high school life can be.

Shi Miao is still stuck with her irresponsible elder brother Shi Fen, who lives in neverending fear of his younger sister's stormy temper. As the siblings continue enjoying their carefree high school days alongside their friends and classmates, they realize that there truly is no cure for family.

Shi Miao has a lot of experience dealing with her older brother's peculiar habits. After all her scolding, it is natural to expect that Shi Fen's antics would come to an end. But having spent their whole life together, it is obvious to Miao that some things never change—and maybe that is for the best. Despite his recklessness, Fen usually means well. As a result, a tight-knit friend group has formed around him and his sister. Joined by their classmates—Kai Xin, Wan Sui, and Miaomiao—the Shi siblings' tenure at high school continues to be an absolute spectacle.
