Lin Yu and Xie Yan have disliked each other since they were children. It seems that from the moment they were born, the two sides have been bound to the system of mortal enemies. I don't know if it was God's intention or what, but amid the wave of demolitions, their community was the only one standing like an isolated island, and on this "isolated island", the war between the two old enemies continued. Although they were not in the same school from elementary school to junior high school, the two would secretly compete to become "other people's children" in the words of each other's parents. Through their efforts, they were both admitted to the best high school in the city with excellent results. Unfortunately, they were assigned to the same sprint class. Although there are many experts in the sprint class, they are each other's only competitors. They don't want anyone to get involved between them, and they don't allow outsiders to get involved. In years of competition, the relationship between the two has long changed...
Concept: It is the love between two strong and independent personalities. They love each other, but they are never attached; they blend, but they never engulf each other.
