Su Wan, the Su family's biological daughter, was adopted by her uncle at a young age. Her mother died with her name cleared of no wrongdoing, while the Su family seized her inheritance and business interests. Forced to take her cousin's place in an arranged marriage meant to bring good fortune, she married Lu Chenyuan, the Lu Group's CEO, who was believed to be permanently paralyzed. The entire city mocked her for being destined to live as a widow in all but name. Little did anyone know that she possessed a lost and extraordinary mastery of traditional Chinese medicine. On their wedding night, she uncovered a conspiracy involving poison deliberately used to paralyze Lu Chenyuan. She extracted the poison in front of everyone and secured the evidence, then joined forces with him. Together, they investigated the truth behind her mother's death ten years earlier, reclaimed the family's stolen business, and turned the tables on everyone who had wronged them, ultimately finding redemption in each other.
