A modern girl falls from a high altitude and accidentally crosses the book to become a royal medical girl from ancient times who has superb medical skills but is exploited by the prince (actually a princess). In order to protect herself, she fights monsters and upgrades.
A modern doctor who wears books and an ambitious woman who vows to be emperor disguises herself as a fifth princess.
The two of them have their own agendas and use each other, but they don't have no feelings for each other. It's just that I love you, power, and myself more.
Intention: I don't have any special intention, I just want to tell everyone that no matter how bad life is, we must work hard to live.
