Cen Qiuyu, an associate professor of the Department of Physics at A University, seems serious, but in fact, he has caught a lot of black history.When I was in kindergarten, I robbed Xiao Qingmei for toys, I quarreled with Xiao Qingmei in elementary school, and I tried to fall in love with Xiao Qingmei when I was in middle school.Later, a new professor came to the Department of Physics. He was young, beautiful and temperamental, with outstanding academic ability. More importantly, Cen Qiuyu felt guilty when he saw her.
