The morning light on the avenue hides the tenderest look of the young man's heart. When Lin Mo pressed the send button with a fried dough stick in his mouth, he would never have imagined that the smiling gaze behind him would become the warmest light in the years to come. He is the most casual academic master in Nancheng No. 1 Middle School. He has fried dough sticks in his left hand and soy milk in his right hand. If he fails to throw away the garbage in the shooting style, he will turn back and pick it up in frustration. Lu Xiao is the cold academic god in everyone's eyes. He always inadvertently sets his sights on the figure walking into the campus in the morning light. From walking side by side in the corridor covered with sycamore leaves, to the tacit understanding of the pen tip crossing the paper in the self-study class; from the distance between the foreheads when discussing the topic, to the edge of the umbrella leaning towards him when we share an umbrella on a rainy day. There was no grand confession, just one evening, when Lu Xiao handed over the notes, his fingertips touched slightly. Lin Mo looked up and looked into his starry eyes. "I've asked this question three times." Lu Xiao's voice was filled with a smile. "Then... Say it again?" Lin Mo's ears quietly turned red. It turns out that the best love is like the light and shadow on the avenue, taking root in the subtleties and spreading in daily life. When you come back to your senses, each other's names have already been written on every page of youth. The flowing water of the two top students is just right sweet.
