Her smile is like a candy

Xu Jingshu, who is in Class One of the second year of high school, doesn't talk much coldly. If she hadn't been taken out by the teacher in the math class, I'm afraid it would be a little transparent in the class.

"Jingshu, was punished by Lao Wei again?" When the head teacher Lao Ma led the transfer student Chu Youning to the door of the class, he saw the familiar figure and said helplessly.
"Uh-huh." Xu Jingshu answered quietly and did not feel embarrassed by the presence of outsiders.

Later, in a monthly examination, Lao Wei looked at Xu Jingshu's perfect scores in other subjects, and then compared with the big questions in his math paper that were almost blank. The party concerned looked out of the window in a daze and roared indisputably: "Xu Jingshu, take the paper out to reflect!" When will you come to my class after reflection!"

So that afternoon, someone saw Chu Youning, the god of learning, in the building. She taught Xu Jingshu mathematics in the self-study room.
