There were a few novels that had sad plots, such as "My Talent is Resurrection","To Alive in the End of the World","The Sin of the Three Thousand Dimensional World","The Fujin Is Not Favoured","No Joy in Prosperous Times","The Black Emperor's Chief's Pure Wife","The Devil's Tenderness","The Sad Death God's Heartless","The Daughter of a Wealthy Family: Uncle, Don't Make Trouble","The Sin of Exiled Humans", and so on. You can choose one of them to read according to your reading preferences. I hope you like this fairy's recommendation. Muah ~😗
