Xu Chaomu was suffering from a terrible toothache after school, and she wasn't sure if it was because she caught a cold. To make matters worse, there was evening self-study that night, so she had no choice but to endure the pain and read.
By nine o'clock in the evening, self-study finally ended, but Xu Chaomu still had to do cleaning duty.
It was like misfortunes never come singly. Watching as all her classmates left one by one, she was left to continue sweeping the floor with a broom and wiping the blackboard with the eraser.
The surroundings were pitch-dark and completely silent, Yu Weiwei had been picked up by Li Beiting to go home, leaving her alone to silently endure the toothache while on duty.
The broom hitting the floor made a "swoosh" sound. The floor was really dirty; those boys would throw trash on the ground after eating.
Just as she finished sweeping and was about to close the windows, suddenly, the classroom door was kicked open.
