Qiao Yun, the legitimate daughter of the prime minister, is a stuttering and gluttonous "little fool" who was married to Qi Wang, a bloodthirsty and brutal king, as a consort to bring him good luck. Everyone expected to see her dead body in the palace, but she miraculously calmed Shen Jue's mania and poison attack with her innocent and unsuspecting nature. The cold-blooded mad king transformed into a wife-protecting maniac. Facing her stepmother's cruelty, the crown prince's schemes, and her stepsister's provocations, Qiao Yun repeatedly broke the villain's defenses with her natural and straightforward approach. Under Shen Jue's extreme doting and domineering protection, she gradually went from being an abandoned child who suffered bullying to becoming his only true love in life.
