Clara Wentworth, the Legitimate First-Born Daughter of the Wentworth Clan, was abducted by her Childhood Male Companion Leo Xavier at the age of ten to pave the way for his Concubine-born Younger Sister. She was branded with a Slave Brand, sold seven times, and nearly died in a Plague Shed. Fifteen years later, she returns to the capital as Imperial Consort Clara, who was enfeoffed as a consort for saving the emperor, and stops the Metropolitan Exam Top Scorer from taking the Imperial Palace Exam with a single sentence. Facing outcry from scholars, kneeling petitions from students, and moral coercion, she advances step by step. Using her birthmark, Slave Brand, sale contracts, silver bell, and testimony from the Female Human Trafficker, she tears apart Leo Xavier's hypocritical mask of being a loyal and righteous man, and uncovers the 15-year-old old case of his Concubine-born Younger Sister destroying evidence and her father hastily declaring her dead. In the end, all the guilty parties receive their due punishment. She lets go of her personal grudge, opens a Women's Medical Hall, and rescues more displaced orphaned girls.
