Five years after graduation, Su Nian dug out the unsent love letter while sorting out her old belongings. By this time, she had become a Chinese teacher. She would occasionally see students in class who secretly followed a certain classmate just like she did back then. Lu Yu, on the other hand, stayed in the north and became an engineer. The two only interacted with each other a few times in the classmate group and never met again. In the end, Su Nian put the love letter back into the box, thinking: "That unspoken love is already the best memory of my youth."
