Let's start at the beginning. Ines is a illegitimate princess of the Zener kingdom(irrelevant). A kingdom that defeated the Levan empire( our main setting happen in this empire). And to humiliate the losing empire they send Ines to marry the Crown prince as a peace treaty knowing they can't refuse.
The Nobles will concoct a plan to make Ines fall in love with Ryan ( the ml) so that she doesn't become the crown princess. Which this Plan will work and cause Fl to kill herself knowing everything was fake and she is now miserable
The things is Fl is special she got a entity attached to her called Kian. He feds on her energy or some crap. And after she dies she gives him to her son.
Kian and her son will work together to revive the dead Fl wipe her memory, and switch her body. While the Ml goes crazy and realize the body of his dead wife is gone
Now our Fl is slowly regaining her memory. Ml is recognizing her. Crown prince know it,s her and now ml took Kian from his son so that he wouldn't be hurt by Kian price to pay.
That's the gist of the story rn

Smb explain bc now I’m confused
