On the top floor of the administrative building of Yinling College, the light in the office is always on. Not because he likes to work overtime, but because he knows that someone is looking at this window under the plane tree on the playground. Chenjiu had been waiting for him for eight years. From the age of ten to the age of eighteen, from the age of eighteen to the age of twenty-two. Wait for him to stand up from that chair, wait for him to walk out of that office, wait for him to walk across the playground, come to you, and say "Let's go home." The sycamore leaves fell twelve times. When the twelfth time was over, he came. This is a story about "waiting" and "waiting", "pushing away" and "holding tight", "cannot say" and "finally done". It took two people who didn't dare to love, after twelve years, finally learned - not to learn to say "I love you", but to learn to extend their hands and not take them back. The sycamore leaves have finished falling, and spring is not far away.
