Let me recommend a few novels to you: Life Is Beautiful in Rebirth, The Little Green Plum in His Heart, The Encyclopedia of Happiness in Rebirth, and Don't Be Too Childish in the Girl of Your childhood sweetheart. These novels all belonged to the modern romance or romantic youth genre. There were elements such as brother and sister love, childhood sweethearts, and reunion after many years. I hope it suits your taste!😗~
