The two have known each other since they were very young. They are good playmates and confidants. They go to school together and learn from each other and improve each other, so that both of them have very good grades.
The good times didn't last long. In the second year of junior high school, Bai Jinnan, who lived next door to Lin Yu, wanted to move away.
It's been four years since I left. When school started that day, a transfer student came to Lin Yu's class. By coincidence, he turned out to be his childhood playmate, Bai Jinnan.
