In the afternoon of September, after the classes were reorganized, Li Sheng'an took out the math homework book after placing his things. When Li Sheng'an erased the auxiliary lines that he had drawn wrongly three times, there was a slight noise at the door of the classroom. A boy in a white shirt walked in, and the sunlight came in diagonally from the window behind him, giving the boy's hair a light gold coating. According to the seating chart, he sat next to Li Sheng'an. Li Sheng'an raised his head suddenly and met the boy's gaze - his eyelashes were very long, his eyes were as clean as a freshly wiped blackboard, and the cover of the textbook he was holding had the words "Jiang Xuhuai" written vigorously on it. When Jiang Xuhuai hung his schoolbag beside the desk, he accidentally knocked off the eraser that Li Sheng had placed beside the desk. The moment he bent down to pick it up, Li Sheng'an caught a glimpse of the handwriting on the sticky note posted in his textbook - it was not the commonly used 0.5Mm black ink pen, but a thinner pen. Even the steps for formula derivation were written in block letters.
Only later did she realize that this "unordinaryness" would become the light that illuminated her wrong answers in the days to come, and also become the direction she tried her best to catch up with.
