As an "abandoned daughter abandoned by her family", the heroine marries a "short-lived and terminally ill prince". The two go from testing each other and acting as pawns to working together to uncover a shocking conspiracy. On the surface, it looks like a political marriage between powerful people, but in fact it is two top players trying to redeem each other and make a comeback in a desperate situation. The whole book is based on "ancient world sentiments", and uses the most traditional shell of house fighting and court intrigue to wrap up a core of "strong women and strong men, running in both directions". The heroine does not rely on time travel, rebirth, or the system, but purely relies on the top-notch wisdom and ruthless methods that the ancient ladies burst out after being forced into a desperate situation.
