The school building's corridors were long enough that Lin Ye and Su Xiaoqing, students in neighboring classes, shared only the occasional passing glance over three years. He was an average student, his grades somewhere in the middle, and spent breaks fooling around at the end of the hall. She was a top student, always near the top of the rankings, her figure often buried behind stacks of exercise books. The two classes between them were like an invisible boundary, keeping their paths apart.
Then, with fifty days left until the college entrance exam, a mix-up in the distribution of study materials sent Lin Ye to knock on Su Xiaoqing's classroom door, a stack of test papers in his arms. Her surprised look as she raised her head, and the slight tremble of his fingertips as he handed them over, became the beginning of their story.
