Exchange Marriage for Sister-In-Law

[The villain is reborn + the female protagonist's perspective is to marry before falling in love + the male protagonist's perspective is that a secret love comes true] She is a dignified and courteous lady, and she only lives to become the Princess of Longevity, to take care of her husband and raise her children. The rebirth of his father changed the direction of his destiny. She became what her father said was a shameless enchantress who brought disaster to the country and the people. My sister was married off, and she was abandoned in the wilderness. A hunter came to his rescue, and she pledged herself to him. I thought I could live a stable life in this life. Little did he know that he was the king of Zhou who his father said was causing harm to the country and the people. Everything is back to square one. "If you kill him, you will still be my daughter." The father made an attractive offer. His eyes were filled with sorrow: Are you going to kill me for something I haven't done? —— The mountains and rivers were in turmoil, the enemy's cavalry trampled the Central Plains, the fertile fields became ruins, and the people were enslaved. She finally became what her father said was a shameless concubine who brought disaster to the country and the people. Faced with her father's accusation and her ex-husband's hatred, she tore into pieces: In this life, whether I am good or evil, a monster or a demon, none of you are qualified to judge me in the name of God. —— The rebirth of his father and his brother made him suffer a lot and he lost his life several times. She looked at him with distressed eyes. His face was covered with bloodstains, but he still smiled and comforted her: It's good to be reborn. At least in this life, you are my wife.
