The original premise is good and well thought out. Like if this was a movie (which would have to actually end at some point...) and somebody told me the premise, I’d go watch it. Because I’d assume that a woman MC who could think the plan through would be at least somewhat enjoyable to watch. Fake dating is great, contract marriages are enjoyable to watch, and the woman actually has political power. Also, the art is gorgeous and the author might have missed their calling as a fashion designer.
The execution is...um... I couldn’t get far past the beginning. I have tried. Multiple times. Take that however you will.
