There are two well-known figures in No. 1 Middle School of Province G. One is Li Jiaying, a science genius who skipped three grades in a row, and the other is the demon king Ye Shiduo who has repeated grades for two years. What is shocking is that Li Shaying, a sister who is equally outstanding as Li Jiaying, actually fell in love with Ye Shiduo. Many people told Li Shaying that being with Ye Shiduo was a sign of self-destruction, but she still liked the unruly boy. Thinking back to those days, Li Shaying wanted to erase this dark history. Being in a relationship with Ye Shiduo might have been the biggest mistake she had ever made in her life. But it had been five years since they broke up, and this guy Ye Shiduo suddenly came out to pester her about what was going on. She would never forgive this scumbag this time...
