After her mother died young, she was framed by her stepmother Liu, and she pretended to be crazy and worked as a fool for three years to protect herself. To the outside world, she was a slurred, stubborn and ignorant "silly lady", but in fact she had an exquisite mind and was proficient in the art of Qihuang and court strategy. She secretly cultivated a team of loyal soldiers who waited for the opportunity to overturn her mother's case.
Male protagonist Xiao Qi: 20 years old, Prince Dayin. On the surface, he is cold and taciturn, not womanizing, and does not speak politely to the concubines in the harem or the daughters of the courtiers. In fact, he is deep-minded. He secretly investigated the cause of Liu Zhixia's mother's death. He had already seen through Liu Zhixia's disguise and calmly resolved the crisis for her many times in the dark.
