The well-known female top student in the school was forced by her class teacher to help Jiang Yu, the most rebellious student in her grade. In the eyes of everyone, Jiang Yu's mud can't hold up the wall, but when Pei Wan was helping him sort out his math problem book, he discovered the confession code written by the other party using "variant polar coordinate equations". What shocked her even more was that the problem-solving ideas hidden in the code words were competition-level problems that even she couldn't solve. It turns out that Jiang Yu is not a scumbag at all, but deliberately hides his strength for some reason. A top student who frantically "encourages studies" in the open but repeatedly hits the wall, and a little "god of study" who crazily exports high-level academic romance in the dark, start a sweet and sour pursuit that only two people can understand, entangled with performance rankings.
