School Belle******************

The plot is so outrageous, so wrong. I just don't understand. Their former class teacher in the first grade of high school clearly knew about their situation and recommended the protagonist to participate in some mathematics competition. Later he became the grade director. It was like a different person. He looked like the protagonist was a bad student. He was also very sure that the writing was terrible, okay? Don't tell the truth

Looks like Lin Zhou and Xu Nianchu
