When it was lunch break, the students all went to the cafeteria to eat together.
Cheng Ling was used to being alone, so she didn't care when she went to eat.
Mingling in the crowd, she went against all and headed to Sun Qi's office.
Sun Qi was a man in his fifties, wearing a pair of round glasses. His hair was not thick, and he never combed it. His hair was always messy, giving people the impression that he was a strange uncle.
Cheng Ling knocked on the door of the office.
Sun Qi was the only one in the office. Sun Qi waved to her, and she walked in.
"Teacher Sun, may I ask why you are looking for me?"
"You are Cheng Ling? You were in class one before, right?"
Sun Qi's desk was not filled with textbooks and homework like the other teachers. His desk was covered with A4 paper. The A4 paper that were filled with drafts, all kinds of formulas, numbers, and letters were piled up together.
