That day, the sky was very blue, and they were sitting side by side in the examination room of the physics competition. The breeze blew the girl's long hair, which was smooth and fragrant. The long hair floated gently with the breeze. Maybe it was not long enough, maybe the wind was in the wrong direction, but it could not touch the arm of the boy on the table next door. He kept doing the questions silently with his eyes lowered, not being disturbed by the things around him at all. At some point, both the boy and the girl fell asleep lying on the table. They were in the same posture and in the same direction. The test papers flipping in the wind were filled with numbers and formulas. The invigilator coughed lightly: "After you have finished, please check carefully and don't do anything else." The boys and girls seemed to be awakened. They looked up at the invigilator blankly, then they all changed directions and fell asleep again in the same position as before. Such tacit and consistent movements seemed to come from one person, but two completely different names were written on the corners of the two test papers flipping in the wind. One is named Xiao Ziyuan. One is called Sui Yi. In such a young and beautiful time, so long ago, they already had such a tacit understanding. That was the first time we met, and I didn't expect you to be so important to me. Reminiscing about the past meeting when we were both young, we didn't know who would be the first to fall in love.
