I have a theory.
What if, the original novel that Daphne told Richard about was a bl love story between Richard and the crown prince. Maybe, in the original timeline due to the "unnatural" nature of their relationship dynamic it was frowned upon and met with persecution by others. However, instead of placing the blame on both parties, everyone placed it solely on Richard, expressing hate and disgust towards him, and subjecting him to terrible mistreatment, which eventually lead to his unfortunate, cruel death. Maybe, that was what that dream Richard had before waking up from the poisoned tea was, a memory of the original timeline. Daphne, who based on this chapter doesn't seem to like the crown prince in that way, espicially not to the point of taking him bac in every timeline, took Richard's place in the novel and wiped everyone's memory of the first timeline, by maaking a deal with the law of the world, in order to protect Richard from his unjust fate. That however, lead to her taking on Richard's fate of constant demise after marrying the crown prince in every timeline. Now, Richard who has time looped 49 times, is trying to save her from her fate without realizing he's actually settting the story straight, and once more becoming the love interest to the crown prince, restoring his oringinal fate, and reversing Daphne's sacrifice for him.
