In the Chinese Department of the first university in H City, there is a beautiful professor. She is gentle, charming, elegant, speaks softly, and is delicate and soft. The students all like this teacher who is good-tempered and eye-catching, but they always feel bored after staying with this teacher for a long time! Because the temperament of this beautiful professor seems to be... A bit stupid! When it is quiet, it is like air. It is said that she is still unmarried and is about to turn 30. She has become an obvious holy (leftover) girl!
