The boy jumped. He almost dropped his pencil and would have jumped out of his chair if he didn't suddenly remember he was still in class.
The teacher looked his way and the boy hurriedly sat straight and pretended to write something in his notebook.
The boy could see there was a furry animal outside the window. Judging by its shadow on the window, he realized it was a black cat.
Zheng Tan was worried the kid would scream or jump out of his seat and draw attention to him. Fortunately, the boy remained calm.
Zheng Tan looked past the boy and surveyed the classroom.
He found Jiao Yuan and his group. They were sitting close to each other in the middle of the classroom. The homeroom teacher assigned them seats that allowed them to see the board clearly without breathing in chalk dust.
Jiao Yuan had no idea at the moment that his cat was spying on him.
Zheng Tan left to check out the teachers' office. He didn't find Mama Jiao, her office was probably on the second floor.
