Rebirth of the Crown Princess on Trial Marriage

As the eldest daughter of an aristocratic family, she was highly regarded and favored by her family when she was born. However, once her mother's family was convicted and her mother was secretly executed by the family, she was detained in the attic. The only reason for her survival was her fat body. She was defenseless and was sold to the Prince of Yan's Palace. She became the trial marriage daughter of Prince Yan's eldest son and a low-status first-in-law. Just like the fate that the first wife should have, she watched helplessly as her son was strangled to death by the wife of the wife, and suddenly she was reborn on the night of the trial marriage. It was not too late. She would plan every step, take revenge, and gradually reach the top!
