😋I recommend you the book,"Dreamtalk Years Flow." The female protagonist was originally a bad student. After she confessed to the male protagonist and was rejected, she became a top student. When she was a graduate student, the male protagonist became the female protagonist's teacher. This was a high school and university love story between two top students. There was not much melodramatic plot, only real emotional interactions between ordinary people. I hope you like my recommendation, Mwah~😗
