I liked comparing this to Red River where the protagonist both time travel from modern day times to ancient civilizations like Egypt and Turkey. In Red River the love interest actually believes the protagonist when she say she from the future, is more tomboyish, and interested in sports eventually marrying a prince turned emperor of Turkey while this protagonist has to cope/deal with there being no intimate partner violence laws, disrespect, and pretty being gas-lighted when it comes to being from the future and seeing glimpses of her time-line. The Pharaoh's aggressive tendencies are lessened overtime (one can even see a softer side), but the author also addresses how the pharaoh's word was law as he was viewed as a god and their was no respect for space when a woman wanted some time with her thoughts. I liked in both that they easily win the favor of the people with their more modern views of royalty really being in place to help the commoners.
