I recommend 'Elegance of the North' to you! The male protagonist was a poor university professor, and the female protagonist was a rich family's daughter. They met and fell in love during their days in the north, crossing the social class gap. Although the female lead had been bullied and the male lead had experienced setbacks, they supported each other and eventually walked towards a beautiful future. This is a sweet novel, with love and friendship, full of characters, and ups and downs in the plot. I believe it will satisfy your taste. I hope you like this fairy's recommendation. Muah ~😗
