Demoting my wife to a concubine? After being reborn, I turned around and married into the imperial f

In her past life, Chu Xunzhen treated her husband Gu Changfeng with all her heart, only to be demoted to a concubine in return.
After her rebirth, she vowed never to have anything to do with him again.
Gu Changfeng thought she would still be waiting for him in the same place, but little did he know that she would marry into the imperial family and become the Ninth Prince's consort.
Her biological mother, Lady Hou, doted on her adopted daughter, only to discover that the adopted daughter was actually born to her husband and a princess from the previous dynasty, whom she despised the most. She was so angry that she vomited blood.
His biological father, Lord Chu, doted on a fake heiress. It turned out she wasn't his daughter with a princess from the previous dynasty, but rather the daughter of the imperial advisor and the princess. He became the cheap sucker who ended up taking her in.
The older brother helped his fake heiress sister, but the fake heiress's true colors were revealed, and she even caused him to become a cripple.
The second brother accepted the fake heiress sister and looked down on the real heiress. Later, his hand was chopped off.
The third brother was infatuated with the fake heiress and attempted to assassinate her, his own sister. As a result, he went blind and was humiliated by the fake heiress.
Her own parents, her eldest, second, and third brothers, and her husband from her past life were all so angry they vomited blood, weeping with regret: "Xunzhen, we all know we were wrong, can you still accept us?"
