In her freshman year of high school, Lin Yining dragged a pink suitcase into the school gate. Someone helped her hold the bottom of the suitcase - and then he sat behind her. They made up classes together, played games, and held hands once in a used bookstore. He said "wait a little longer", and she really did. Wait until your best friend turns around and walks onto someone else's path, wait until the gossip in the corridor drowns out the sound of the wind, wait until he stands still and doesn't come over.
Later she walked the rest of the way alone. Ginkgo trees are green and yellow, yellow and fall, and fall and grow. On the day of graduation, she took off the ginkgo leaf pendant around her neck and put it in the drawer with her old things. Some days are for remembering, not for going back.
This is a true story - it happened in a certain high school, in a certain corridor, under a certain ginkgo tree. Some people wait three years to learn not to look back, and some people wait three years to wait for someone who is coming. If you have ever walked in a person's hallway for a long time, you will recognize every leaf in it.
