The once sweet and ambiguous relationship between teacher and student ended abruptly in the face of reality. See you again in ten years, fulfilling each other's thoughts and the blue sea and blue sky. I have loved you for six years and determined to become a qualified people's teacher and accompany you. You wait for me for six years, wait for me to grow up, marry me and go home. And I am far away. See you again in ten years. Things are the same and people are not the same. I am willing to use the rest of my life to make up for the mistake of leaving ten years ago, okay?
