At the beginning of his sophomore year of high school, transfer student Su Wanxing had just entered Xingyu Middle School and formed a "liangzi" with Lu Yu, the famous "aloof academic god" in the school - the ice cola he accidentally spilled soaked through his competition notes. I thought they were enemies, but unexpectedly they were assigned to the same class and desk. Su Wanxing's carefree temperament broke the alienation around Lu Yu. She would secretly stuff him candy hidden in her schoolbag, hand him warm milk when he stayed up late to study questions, and make a lot of jokes by dragging him to participate in the campus charity sale. Lu Yu also inadvertently made exceptions for her, helping her with partial math lessons, silently clarifying when she was troubled by rumors, and running the last 800-meter lap with her in the summer night wind. When the excitement of adolescence quietly sprouts, expectations from family, pressure to enter higher education, and ignorant misunderstandings follow one after another. From tearing each other down to protecting each other, from school uniforms to wedding dresses, they used the purest love to prove: The luckiest thing in youth is that when the wind blows across the playground in the summer night, I happened to meet your star.
