Guardian my dear, I was thinking, maybe it is a fun idea to lets say, Make Lucia and Anora be the reincarnations of the girls that deceived Thanathos and Hypnos into joining hades or something and that they actually are angels and stuff and that like, only they can actually give back the words too the book by finding out who they are and starting the relationship with the gods. [ that like, the next morning a few words that are written with the blood on Hypnos are back because he saved Anora and a few words or sentences from Thanathos his blood are back because Thanathos and Lucia kissed ] But that if they find out how it works, it will only work as they kiss or save each other without planning too.
