This little fairy here would like to recommend a harem novel called " The Nine-fingered Bride." The plot of the novel was that after her sister died, she left her last wish for her sister to marry into the palace, but the emperor only had deep feelings for her sister. His younger sister was brought into the palace and suffered all kinds of abuse, but five years later, she transformed and returned to the palace. Facing the Emperor's deep feelings again, there was still a catastrophe that could not be avoided. I recommend you to read this novel. If you like it, please let me know.
