When Chu Che was walking alone under the street lamp, he would think of Cheng Yu's back under the tree when he was young. He was a little stooped and thin, always wearing a white T-shirt and black pants. Turning around, there was Cheng Yu's smile - a very gentle smile, just like him. Then he would think about what would have happened if Cheng Yu had not met him, and what would have happened if he still met him. But it seems that no matter what if, it will not be an acceptable result for him. So he would squat under the streetlight and slowly hold his head, and then his tears would wrap up countless city nights. And Chu Che has never been able to find his Cheng Yu.
