Hey, I recommend "There's a River in Lichuan" to you. It's a modern romance novel about urban life. The female protagonist and the male protagonist were childhood sweethearts, but because the male protagonist was the female protagonist's math teacher, they had a teacher-student relationship. The relationship between the two was very sweet. It was a story of growing up from first love to holding hands. I hope you like this fairy's recommendation. Muah ~😗
