From the first page to the last page of the sketchbook, Lin Michuan's name is all over it. Erase it when it's full, and change it if it's scratched. The iron box is rusty and was picked up. The items inside were all "worthless", including faded candy wrappers, fallen buttons, smoked cigarette butts, and post-it notes. But the sum of these things makes Shen Yi's whole youth throb. It wasn't worth much, but he couldn't bear to throw it away.
Intention: He stood in front of me and said "I really mean it". Later, these words became the only voice I could hear for the rest of my life.
