Orphan Iris was once treated kindly by Wynne Sterling, the legitimate daughter of the Ningyuan Marquis Manor. Wynne was framed by her family elders and concubine-born younger sister, falling into dire straits. Iris learned poison and medical skills, disguised herself as Wynne using a human skin mask, returned to the marquis manor, and was forced to marry Crippled Prince Hale Royce. The two tested each other and worked together to deal with various schemes. In the midst of the crisis, Hale Royce discovered her secret and silently protected her. After the turmoil subsided, Iris took off her disguise and confessed her true identity. Hale Royce did not care about her appearance, the two resolved their estrangement, traveled the mountains and rivers together, and practiced medicine to help the world.
