Su Nianyin was dismissed from three schools in a row, and her grandmother begged the principal for a long time before she was allowed to transfer to Qingshi Middle School. On the first day of school, she became roommates with Shen Yanzhou, who was number one in grade. She just wanted to hang around and wait for graduation, but unexpectedly heard Shen Yanzhou say to the class teacher in the office: "Let her stay, I will teach." Su Nian decided to transfer to another school, and Shen Yanzhou came up with a "passing line contract" - "Next monthly exam, you will pass math. If you fail, you will not be allowed to transfer." From then on, the two began to "forced to make up lessons". Shen Yanzhou discovered that Su Nian was actually very smart, but had severe test anxiety. Su Nian took his studies seriously for the first time, and discovered for the first time that Shen Yanzhou was not as perfect as he appeared. Su Nian accidentally discovered Shen Yanzhou's family situation - the relationship between his parents was cold. She began to care about him in turn. The relationship between the two has changed from "tutoring partners" to "mutual support". On Shen Yanzhou's birthday, his parents forgot about it. "This is the best midterm exam I have had in the past few years. Su Nian scored 65 points in the math test and passed for the first time. The relationship between the two has also quietly changed." Su Nian found that he fell in love with Shen Yanzhou. Just when she was hesitant to say anything, Shen Yanzhou spoke first - he wrote in her homework book: "If you make progress in the next exam, I have a question to ask you." When the class teacher asked for an interview, Shen Yanzhou's parents strongly opposed it, and her grandmother was worried that she would be injured. Shen Yanzhou told his parents his true thoughts for the first time. During the senior year sprint, the two of them reviewed together, solved questions together, and ate together. Su Nian went from the bottom to the top 15 in the class. The day before the college entrance examination, Shen Yanzhou said: "If you don't do well in the exam, I will go to your city."
Philosophy: The Bingshan student who is number one in the grade and the transfer student who just wants to hang out are forced to become roommates. He made a ridiculous agreement for her that "you are not allowed to transfer to another school if you fail to pass the exam" - not to trap her, but because he was afraid that she would leave and he would return to a world of his own.
