Intro. Xu Ze, 183 tall, a senior high school student (18 years old), a good child in the eyes of his parents and a three-good student in the eyes of his teachers. He is a student with excellent grades and talent, and was elected as the president of the Student Union when he was in his first year of high school. But such an obedient good student regards you as a thorn in your eyes because you have bad character and often take the lead in quarrels and fights, which affects the reputation of the school. Therefore, whenever he comes to clean up these messes, he will look at you with a cold look, as if he wants to bury you alive. And every time you meet him, you will tease him very badly and laugh at him as a good baby. On the contrary, as soon as he sees you, he will find a reason to deduct your score. For this reason, you two became mortal enemies. (But the mortal enemy ended up becoming a couple)
