How to start...
One is the prince of the current dynasty, and the other is the daughter of the military minister of the current dynasty (it can be regarded as the ancient version of □□).
Two people were given a marriage, and there was no escape from marriage or proxy marriage (you have seen a lot of escape from marriage or proxy marriage)
The two got married smoothly, focusing on their post-marriage life (the royal marriage is very complicated, okay?)
Then, what makes them cherish each other like a couple of gods, and what makes them so close to each other?
Finally, I haven't thought about the ending yet.
