That's 5 Points Missing

Jiang Chen and Jiang Yu are inseparable brothers, and they are also the weirdest couple in the grade. Because regardless of the big test or the small test, his younger brother Jiang Yu's score will always be 5 points higher than his elder brother's, not one point more, not one point less. These five points are the brother's pride and an unspeakable secret between them. It wasn't until his senior year in high school that his brother Jiang Chen suddenly took a long leave without warning. In the examination room, Jiang Yu, who was missing that "reference object", was horrified to find that he couldn't even understand the most basic questions. With trembling hands, he hid the answer under the paper for the first time. However, when the bell rang for the end of the exam, Jiang Chen sent a text message—— "Stop copying. I'm asking for leave because I plan to let go." It turns out that my brother has always known the secret of always being 5 points shorter than him.
