She comes from the 21st century. An accident caused her to travel through time and be reborn as the daughter of a prime minister. That year, she fell in love with him at first sight and married him just to live together forever.
He, a prince, had experienced many betrayals and intrigues since childhood, and he had since become a model of a ruthless emperor. He only married her as his concubine because her father was his father's most trusted prime minister, and she was just a pawn he used to seize the throne.
Seven days after entering the palace, news came out that the princess was favored one after another.
She liked his favor, and was even more moved by his actions, but she never knew the use behind his back.
He loves her, dotes on her, and creates a peach forest for her, just because he uses her to gain benefits, but he doesn't realize that he has already become one with this character.
"Princess, you are just a chess piece."
When she accidentally discovered the fact, she was caught off guard.
