Lin Wanxing, from Class 3, Grade 2, is recognized by the whole class as a "difficult mathematician" - there are more red crosses than correct answers on every monthly math test paper, and the pile of scratch paper can be used as a pillow, but he can even calculate the simplest function question three times wrongly. In order not to hold the class back, the head teacher put her into a "one-to-one support group", and the person she helped was Jiang Xubai, who was first in grade, always sat by the window to answer questions, and even spoke with a "cold and aloof attitude".
Lin Wanxing originally thought this would be a "torture": she was afraid that her clumsiness would disturb Jiang Xubai, and she was even more afraid that the other party would dislike her math skills. But after getting along with her, I realized that Jiang Xubai was not a "cold scholar" at all - he would break down complex formulas into "snack metaphors", patiently hand over a brand new piece of draft paper when she made a mistake, and would even silently tilt his umbrella towards her on rainy days, with half of his shoulders getting wet.
Until an accident, Lin Wanxing picked up Jiang Xubai's wrong answer book that he left in the classroom. He wanted to help him sort out the wrong questions, but found a secret on the last page: there were no math questions in the book, only the dense "Lin Wanxing" and a line of small words - "When she calculated the wrong function, the way her eyelashes drooped was cuter than the correct answer."
It turned out that from the first time she secretly poked his back with a rubber in math class and asked, "How do you solve this problem?", His heartbeat had been quietly written into the wrong question book. This is a campus story about a "girl who is a bad student" and a "boy who is a top student", slowly getting closer and running in both directions between wrong questions and scratch paper, in the morning light and evening breeze of the classroom.
