Have you ever met someone who changed your life at some point in your life? To Yan Xi, Gu Zexi was that person, the person who came with the light. Yan Xi probably never thought that he would get to know this shining person who only lived in other people's mouths in his freshman year, let alone that he would pursue the light for ten years.
Intention: Perhaps most of us will meet a very good person, and then want to become a better version of ourselves because of him or her.
