I recommend the two books,"The Net King: Edogawa Sakurazu-ichi" and "The School Hunk Is A Teacher: A Cold-looking Assistant Teacher, Please Give Me Questions". The female protagonist of "The King of the Net: Edogawa Sakurazu-ichi" was the king of the Qingxue Women's Network. She was a genius and had the plot of being an assistant teacher at Lihai University. The female lead of "School Hunk Is a Teacher: Cold-hearted Teaching Assistant, Please Give Me a Question", Chen Che, was a cute and funny Weibo celebrity and also a teaching assistant. These two books have plots of female geniuses and teaching assistants. They are also light novels and youth campus novels. I believe you will like them. I hope you like this fairy's recommendation.
