Rebirth: Back to the Day Before the Public Exam

I was reborn, back to the day before the public exam. In my previous life, my boyfriend who I had been dating for seven years from high school to college fell in love with the guy who was in the same position as me and ranked first in the rankings with a total score of 0.1 Points ahead of mine. He was also my best friend and roommate for four years in college. My boyfriend's mother, a wealthy businessman, even came to her door to propose marriage seven months ago. In my previous life, I waited for seven years before her mother relented. On the first day of my rebirth, I backhandedly added the WeChat message of Yu Zhou, a teacher from my public examination tutoring agency. If I remember correctly, it is not accurate to say that my best friend is the first on the list, because Yu Zhou is the real first for this position. For some reason, he gave up this position, and my best friend was able to fill in. If I do it again, I will make the betrayer pay the price! Intention: The day before I am reborn and return to the public examination, I want revenge!
