Shi Miao is experienced in managing her brothers unusual behavior. After scolding him, she expects Fen's antics to stop. However, since they have spent their entire life together, she understands that some things remain unchanged and perhaps it's for the better. Despite his carelessness, Fen has good intentions. This has resulted in a close-knit group of friends around them, including Kai Xin, Wan Sui, and Miaomiao. Their time at high school continues to be entertaining due to their unique personalities.
