Mu Jin originally wanted to spend three years in high school without any restrictions, but things never went as he wished, so he entered Class A in his sophomore year of high school.
In his freshman year of high school, he was not in the same class as Shang Ning due to some issues, so he was very willing to join Class A, after all, he could study with her.
